En aras de contener el comunismo y expandir la cultura norteamericana y los valores de democracia y libertad, Estados Unidos lanzó una estrategia de política exterior denominada la Diplomacia del Jazz, que consistía en promocionar internacionalmente el jazz mediante dos artificios: primero, la celebración de conciertos de los intérpretes más representativos de este género en diferentes partes del mundo; y segundo, la trasmisión de programas radiales sobre jazz en emisoras de difusión internacional y así poder mostrar la “superioridad” cultural de su país en detrimento de la otra superpotencia, la Unión Soviética. De este modo, la presente monografía tiene como fin estudiar de qué manera se instrumentalizó dicha estrategia como un medio para proyectar positivamente la imagen de los EEUU durante la Guerra Fría, concretamente entre 1954 y 1968, a partir de la teoría del realismo progresivo de Joseph Nye.

This paper examines the case of a controversial beer advertisement which was promulgated in Bulgaria in 2001, and which provoked eight lawsuits against the brewery, its advertising agency, and the Bulgarian National Television. The case set a precedent in Bulgaria and generated considerable public interest and debate. To the best of the authors’ knowledge this is the first case in Eastern Europe when individuals have challenged companies in the courts of law because of offence caused by an advertisement. The present study discusses how the public bodies responsible for protecting consumer interests and the courts of first instance assessed the advertisement in the context of Bulgarian public policy regarding offensive advertising.

With a 20 million dollar budget and 1,900 staff Voice of America broadcasted in 45 different languages and Italy was one of its main targets. By looking into what went on behind the microphone, this article addresses the extent to which cultural change was planned and structured transnationally, the interactions and interdependencies operating between Washington and Rome, and how a cooperation was achieved despite the fierce resistance of some of RAI’s executives. This allowed to air programmes produced in New York, and led to the launch of the most popular character of Italian radio and television: Mike Bongiorno.
Modernidade e integração na Amazônia: "intelligentsia" e "broadcasting" no entre guerras, 1923 -1937
Resumo:
Modernidade e integração na região chamada Amazônia, vez ou outra, sempre ouvimos na mídia, nos meios intelectuais, entre políticos das mais variadas tendências, do Norte e de outras regiões do país, e surgem questionamentos sobre qual o melhor caminho para a Amazônia. Projetos e ideologias foram criados, normalmente girando em torno das possibilidades de modernidade e integração para a região, há muito considerada reserva de lendas e minérios, o reino da floresta e da "planície", espaço isolado, distante, verdadeiro "vazio" de "éden tropical" ou "inferno verde". Desde os embates na Colônia e no Império sobre integrar ou separar do poder central até aos grandes projetos nos anos de 1970, a intelligentsia local e os meios de comunicação manifestaram ponto de vistas e assumiram, em muitos casos, posicionamentos políticos, principalmente a partir dos séculos XIX e XX. Tentei entrar um pouco nesse debate, reportando-me às primeiras décadas do século XX, e encontrando nesse passado, personagens que espelham os novos atores do presente: os intelectuais e o meio de comunicação mais moderno do entre guerras, ao lado do cinema, o rádio.

In questa tesi ci focalizzeremo sul connubio TV ed internet che rivoluzionerà l’erogazione dei servizi verso i telespettatori e di conseguenza il marketing pubblicitario in questo contesto. Partiremo dalla storia della televisione in Italia e dei dispositivi TV per poi analizzare i primi fenomeni di utilizzo televisivo del canale web e la conseguente nascita dei primi social media e servizi di video on demand. La seconda parte di questa tesi farà una larga panoramica sul marketing televisivo ed il web marketing, fino ad arrivare al punto di massima prossimità tra i due canali, ovvero l’advertising correlato ai contenuti video presenti sul web. Nella terza ed ultima parte analizzeremo le prime piattaforme di WebTV e servizi di internet television, per poi focalizzarci sui probabili risvolti e prospettive future sia a livello di fruizione dei contenuti che pubblicitario. Questo fenomeno avrà una netta influenza nel Marketing considerando che dal 1984 la TV è il mezzo che raccoglie la maggior parte degli investimenti pubblicitari ed il web è il media in maggiore ascesa a livello di penetrazione e popolarità negli ultimi anni.

Innovations in hardware and network technologies lead to an exploding number of non-interrelated parallel media streams. Per se this does not mean any additional value for consumers. Broadcasting and advertisement industries have not yet found new formats to reach the individual user with their content. In this work we propose and describe a novel digital broadcasting framework, which allows for the live staging of (mass) media events and improved consumer personalisation. In addition new professions for future TV production workflows which will emerge are described, namely the 'video composer' and the 'live video conductor'.

Interactive TV technology has been addressed in many previous works, but there is sparse research on the topic of interactive content broadcasting and how to support the production process. In this article, the interactive broadcasting process is broadly defined to include studio technology and digital TV applications at consumer set-top boxes. In particular, augmented reality studio technology employs smart-projectors as light sources and blends real scenes with interactive computer graphics that are controlled at end-user terminals. Moreover, TV producer-friendly multimedia authoring tools empower the development of novel TV formats. Finally, the support for user-contributed content raises the potential to revolutionize the hierarchical TV production process, by introducing the viewer as part of content delivery chain.

Television and movie images have been altered ever since it was technically possible. Nowadays embedding advertisements, or incorporating text and graphics in TV scenes, are common practice, but they can not be considered as integrated part of the scene. The introduction of new services for interactive augmented television is discussed in this paper. We analyse the main aspects related with the whole chain of augmented reality production. Interactivity is one of the most important added values of the digital television: This paper aims to break the model where all TV viewers receive the same final image. Thus, we introduce and discuss the new concept of interactive augmented television, i. e. real time composition of video and computer graphics - e.g. a real scene and freely selectable images or spatial rendered objects - edited and customized by the end user within the context of the user's set top box and TV receiver.

Objectives: The aim of this content analysis study is to characterize the TV advertisements aired to an at-risk child population along the Texas-Mexico border. Methods: We characterized the early Saturday morning TV advertisements aired by three broadcast network categories (U.S. English language, U.S. Spanish language, and Mexican Spanish language) in Spring 2010. The number, type (food related vs. non-food related), target audience, and persuasion tactics used were recorded. Advertised foods, based on nutrition content, were categorized as meeting or not meeting current dietary guidelines. Results: Most commercials were non-food related (82.7%, 397 of 480). The majority of the prepared foods (e.g., cereals, snacks, and drinks) advertised did not meet the current U.S. Dietary Guidelines. Additionally, nutrition content information was not available for many of the foods advertised on the Mexican Spanish language broadcast network category. Conclusions: For U.S. children at risk for obesity along the Texas-Mexico border exposure to TV food advertisements may result in the continuation of sedentary behavior as well as an increased consumption of foods of poor nutritional quality. An international regulatory effort to monitor and enforce the reduction of child-oriented food advertising is needed. Editors' Note: This article was submitted in response to the first issue of the Journal of Applied Research on Children: Latino Children.

Public broadcasting has always been a regulatory field somewhat zealously guarded within the nation states' sphere and kept willingly untouched by regional or international rules. Values inherent to the role of public broadcasting, such as cultural and national identity, social cohesion, pluralism and a sustained public sphere, were thought too critical and too historically connected with the particular society to allow any "outside" influence. Different regulatory models have emerged to reflect these specificities within the national boundaries of European countries. Yet, as media evolved technologically and economically, the constraints of state borders were rendered obsolete and the inner tension between culture and commerce of the television medium became more pronounced. This tension was only intensified with the formulation of a European Community (EC) layer of regulation, which had as its primary objective the creation of a single market for audiovisual services (or as the EC Directive beautifully put it, a "Television without Frontiers"), while also including some provisions catering for cultural concerns, such as the infamous quota system for European and independent productions. Against this backdrop, public broadcasting makes a particularly intriguing subject for a study of regulatory dilemmas of national versus supranational, integration versus intergovernmentalism, culture versus commerce, intervention versus liberalisation, and all this in the dynamic setting of contemporary media. The present paper reviews Irini Katsirea's book PUBLIC BROADCASTING AND EUROPEAN LAW and seeks to identify whether all elements of the complex governance puzzle of European public service broadcasting rules are analytically well fitted together.

Much has happened in the past fifty years, and the broadcasting system and in fact the entire media landscape have changed in many significant ways. Yet, the debate on the role of public service media and the involvement of the state in them still perseveres. It has indeed been reinvigorated due to the tectonic shifts in media production, distribution, access and consumption caused by digital technologies in general, and the Internet in particular. The gist of the debates has however curiously remained almost the same and is still focused on a set of economic arguments that call for state intervention in public media, and not unimportantly, on the various political interpretations of these economic arguments. In Europe, the debate has another essential core too, as Public Service Broadcasting (PSB) has been traditionally entrusted to serve some higher goals intrinsically related to key democratic and cultural processes. Accordingly, PSB in Western Europe has developed as the core media institution at the national level and has become deeply embedded in many facets of the nation’s economic, political, social and cultural life. Against the backdrop of PSB’s history, its vital tasks in society, as well as the dramatic changes brought about by the digitally networked environment, the question on the future of PSB and its transition into Public Service Media (PSM) is very interesting, to say the least, and highly challenging at the same time. The book by Karen Donders, Public Service Media and Policy in Europe (Palgrave, 2012), makes an essential contribution to these complex debates, and more importantly, adds some new value to an otherwise saturated discourse.

El estándar LTE se ha posicionado como una de las claves para que los operadores de telecomunicación puedan abordar de manera eficiente en costes el crecimiento de la demanda de tráfico móvil que se prevé para los próximos años, al ser una tecnología más escalable en el núcleo de la red y más flexible en la interfaz radio que sus predecesoras. En este sentido, es necesario también que los reguladores garanticen un acceso al espectro radioeléctrico adecuado, equitativo y no discriminatorio, que permita un entorno estable para el despliegue de redes de comunicaciones móviles avanzadas. Además de la flexibilización del marco regulador del espectro radioeléctrico en Europa, que ha permitido el despliegue de nuevas tecnologías en las bandas de frecuencia históricas de GSM, se ha puesto a disposición espectro adicional para sistemas IMT en nuevas bandas de frecuencia, lo que ha planteando a su vez nuevos retos para la tecnología y la regulación. La fragmentación del espectro disponible para comunicaciones móviles ha impulsado el desarrollo de técnicas de agregación de portadoras en las nuevas versiones del estándar LTE, que permiten explotar mejor los recursos radio en su conjunto. No obstante, el espectro inferior a 1 GHz sigue siendo escaso, ya que el tráfico móvil aumenta y la banda de 900 MHz aún se utiliza para servicios GSM, lo que no ha conseguido sino agravar la disputa entre los servicios de radiodifusión terrestre y de comunicaciones móviles por la parte superior de la banda UHF. En concreto, la banda de 700 MHz se perfila como una de las próximas para aumentar el espectro disponible para los servicios en movilidad, si bien su liberación por parte de las actuales redes de Televisión Digital Terrestre presenta no pocas dificultades en los Estados miembros en los que ésta es la principal plataforma audiovisual de acceso gratuito, abriendo un debate sobre el modelo audiovisual a largo plazo en Europa. Por otro lado, las políticas públicas de promoción del acceso a la banda ancha rápida y ultrarrápida de la presente década han establecido objetivos ambiciosos para el año 2020, tanto en el ámbito europeo como en los diferentes Estados miembros. La universalización del acceso a redes de banda ancha de al menos 30 Mbps constituye uno de los principales retos. Las expectativas generadas por la tecnología LTE y la puesta a disposición de nuevas bandas de frecuencia hace posible que los servicios de acceso fijo inalámbrico adquieran especial relevancia ante los objetivos de política pública establecidos que, como ha sido reconocido en diversas ocasiones, no podrán lograrse sino con un compendio de diferente tecnologías. Para esta Tesis Doctoral se han desarrollado una serie modelos tecnoeconómicos con el objetivo de realizar un análisis prospectivo que evalúa tres casos de especial relevancia en el despliegue de redes LTE: en primer lugar, la valoración económica de la banda de 700 MHz; en segundo lugar, la evaluación de modelos de negocio y reducción de costes considerando tecnologías femtocelulares; y finalmente, la viabilidad de las redes LTE de acceso fijo inalámbrico para el cierre de la brecha digital en el acceso a la banda ancha de 30 Mbps. En relación con la aplicación del análisis tecnoeconómico para la valoración del espectro de 700 MHz, los resultados obtenidos ponen de manifiesto dos cuestiones fundamentales. En primer lugar, la necesidad de asignar a los operadores más espectro para satisfacer las previsiones de demanda de tráfico móvil a medio plazo. En segundo, existe una diferencia notable en los costes de despliegue de una red LTE cuando se dispone de espectro en frecuencias inferiores a 1 GHz y cuando no, pero esta diferencia de costes disminuye a medida que se añade nuevo espectro sub-1GHz. De esta manera, la atribución de la banda de 700 MHz a servicios de comunicaciones móviles supone una reducción relevante en los costes de despliegue si el operador no dispone de espectro en la banda de 800 MHz, pero no así si ya dispone de espectro en bandas bajas para el despliegue. En este sentido, puede concluirse que el precio que los operadores estarán dispuestos a pagar por el espectro de la banda de 700 MHz dependerá de si ya tienen disponible espectro en la banda de 800 MHz. Sin embargo, dado que la competencia por ese espectro será menor, los ingresos esperables en las licitaciones de esta nueva banda serán en general menores, a pesar de que para algunos operadores este espectro sería tan valioso como el de 800 MHz. En segundo lugar, en relación con el despliegue de femtoceldas pueden extraerse algunas conclusiones en términos de ahorro de costes de despliegue y también de cara a la viabilidad de los modelos de negocio que posibilitan. El ahorro que supone la introducción de femtoceldas en el despliegue de una red LTE frente al caso de un despliegue exclusivamente macrocelular se ha demostrado que es mayor cuanto menor es el ancho de banda disponible para la red macrocelular. En esta línea, para un operador convergente el despliegue de femtoceldas tiene sentido económico si el ancho de banda disponible es escaso (en torno a 2x10 MHz), que, en el caso de España, puede reflejar el caso de los operadores del segmento fijo que son nuevos entrantes en el móvil. Por otro lado, los modelos de acceso abierto son interesantes para operadores exclusivamente móviles, porque consiguen flexibilizar los costes sustituyendo estaciones base macrocelulares por el despliegue de femtoceldas, pero necesitan desplegarse en zonas con una densidad de población relativamente elevada para que éstas descarguen tráfico de varios usuarios de la red macrocelular simultáneamente. No obstante, las femtoceldas son beneficiosas en todo caso si es el usuario quien asume los costes de la femtocelda y el backhaul, lo que sólo parece probable si se integran en el modelo de negocio de comercialización de nuevos servicios. Por tanto, el despliegue de femtoceldas en buena parte de la casuística estudiada sólo tiene sentido si consiguen aumentar los ingresos por usuario comercializando servicios de valor añadido que necesiten calidad de servicio garantizada y exploten a la vez de esa forma su principal ventaja competitiva respecto a la tecnología WiFi. Finalmente, en relación con el papel de la tecnología LTE para la provisión de servicios de acceso fijo inalámbrico para la banda ancha de 30 Mbps, se ha desarrollado un modelo TD-LTE y mediante la metodología de análisis tecnoeconómico se ha realizado un estudio prospectivo para el caso de España. Los resultados obtenidos preciden una huella de cobertura de FTTH del 74% para 2020, y demuestran que una red TD-LTE en la banda de 3,5 GHz resulta viable para aumentar la cobertura de servicios de 30 Mbps en 14 puntos porcentuales. Junto con la consideración de la cobertura de otras redes, la cobertura de 30 Mbps de acuerdo a la viabilidad de los despliegues alcanzaría el 95% en España en el año 2020. Como resumen, los resultados obtenidos muestran en todos los casos la capacidad de la tecnología LTE para afrontar nuevos desafíos en relación con el aumento del tráfico móvil, especialmente crítico en las zonas más urbanas, y el cierre de la brecha digital en el acceso a la banda ancha rápida en las zonas más rurales. ABSTRACT The LTE standard has been pointed out as one of the keys for telecom operators to address the demand growth in mobile traffic foreseen for the next years in a cost-efficient way, since its core network is more scalable and its radio interface more flexible than those of its predecessor technologies. On the other hand, regulators need to guarantee an adequate, equitable and non-discriminatory access to radio spectrum, which enable a favorable environment for the deployment of advanced mobile communication networks. Despite the reform of the spectrum regulatory framework in Europe, which allowed for the deployment of new technologies in the historic GSM bands, additional spectrum has been allocated to IMT systems in new frequency bands, what in turn has set out new challenges for technology and regulation. The current fragmentation of available spectrum in very different frequency bands has boosted the development of carrier aggregation techniques in most recent releases of the LTE standard, which permit a better exploitation of radio resources as a whole. Nonetheless, spectrum below 1 GHz is still scarce for mobile networks, since mobile traffic increases at a more rapid pace than spectral efficiency and spectrum resources. The 900 MHz frequency band is still being used for GSM services, what has worsen the dispute between mobile communication services and terrestrial broadcasting services for the upper part of the UHF band. Concretely, the 700 MHz frequency band has been pointed out as one of the next bands to be allocated to mobile in order to increase available spectrum. However, its release by current Digital Terrestrial Television networks is challenging in Member States where it constitutes the main free access audiovisual platform, opening up a new debate around the audiovisual model in the long term in Europe. On the other hand, public policies of the present decade to promote fast and ultrafast broadband access has established very ambitious objectives for the year 2020, both at European and national levels. Universalization of 30 Mbps broadband access networks constitutes one of the main challenges. Expectations raised by LTE technology and the allocation of new frequency bands has lead fixed wireless access (FWA) services to acquire special relevance in light of public policy objectives, which will not be met but with a compendium of different technologies, as different involved stakeholders have acknowledged. This PhD Dissertation develops techno-economic models to carry out a prospective analysis for three cases of special relevance in LTE networks’ deployment: the spectrum pricing of the 700 MHz frequency band, an assessment of new business models and cost reduction considering femtocell technologies, and the feasibility of LTE fixed wireless access networks to close the 30 Mbps broadband access gap in rural areas. In the first place and regarding the application of techno-economic analysis for 700 MHz spectrum pricing, obtained results reveal two core issues. First of all, the need to allocate more spectrum for operators in order to fulfill mobile traffic demand in the mid-term. Secondly, there is a substantial difference in deployment costs for a LTE network when there is sub-1GHz spectrum available and when there is not, but this difference decreases as additional sub-1GHz spectrum is added. Thus, the allocation of 700 MHz band to mobile communication services would cause a relevant reduction in deployment costs if the operator does not count on spectrum in the 800 MHz, but not if it already has been assigned spectrum in low frequencies for the deployment. In this regard, the price operators will be willing to pay for 700 MHz spectrum will depend on them having already spectrum in the 800 MHz frequency band or not. However, since competition for the new spectrum will not be so strong, expected incomes from 700 MHz spectrum awards will be generally lower than those from the digital dividend, despite this spectrum being as valuable as 800 MHz spectrum for some operators. In the second place, regarding femtocell deployment, some conclusions can be drawn in terms of deployment cost savings and also with reference to the business model they enable. Savings provided by a joint macro-femto LTE network as compared to an exclusively macrocellular deployment increase as the available bandwidth for the macrocells decreases. Therefore, for a convergent operator the deployment of femtocells can only have economic sense if the available bandwidth is scarce (around 2x10 MHz), which might be the case of fix market operators which are new entrant in mobile market. Besides, open access models are interesting for exclusively mobile operators, since they make costs more flexible by substituting macrocell base stations by femtocells, but they need to be deployed relatively densely populated areas so that they can offload traffic from several macrocell users simultaneously. Nonetheless, femtocells are beneficial in all cases if the user assumes both femtocell and backhaul costs, which only seems probable if they are integrated in a business model commercializing new services. Therefore, in many of the cases analyzed femtocell deployment only makes sense if they increase revenues per user through new added value services which need from guaranteed quality of service, thus exploiting its main competitive advantage compared to WiFi. Finally, regarding the role of LTE technology in the provision of fixed wireless access services for 30 Mbps broadband, a TD-LTE model has been developed and a prospective study has been carried out through techno-economic methodology for the Spanish case. Obtained results foresee a FTTH coverage footprint of 74% households for 2020, and prove that a TD-LTE network in the 3.5 GHz band results feasible to increase 30 Mbps service coverage in additional 14 percentage points. To sum up, obtained results show LTE technology capability to address new challenges regarding both mobile traffic growth, particularly critical in urban zones, and the current digital divide in fast broadband access in most rural zones.

From the Introduction. The Media Sector has experienced a technological revolution in the last 15 years. Digital encoding of television signals made possible a more efficient use of the radiospectrum. Digital terrestrial television (hereinafter, “DTT”) allows now for the reception of a significant number of free-to-air channels.1 Moreover, the use of new transmission platforms (hereinafter,“platforms”), namely cable and direct-to-home satellite (hereinafter, “DTH”) paved the way for the arrival in Europe of pay-TV operators, which finance their activities mainly via subscription fees. This changing technological landscape is subject to further evolution in the near future, as incumbent telecommunications operators become increasingly interested in making available broadcasting content2 as part of their broadband offer and 3G mobile handsets can be used for the reception of TV signals....The present paper seeks to ascertain whether the Commission “regulatory approach” towards the exclusive sale of premium content is a sound one, in particular in view of the constant technological evolution outlined above. The assumptions underlying landmark Commission decisions will be compared with recent developments of the media sector in Italy. In the NewsCorp./Telepiù case, decided in 2003, the Commission imposed very strict conditions to allow the merger giving birth to Sky Italia, on the assumption that the operation created a lasting near-monopsony in the different upstream markets for the acquisition of premium intervened against the media conglomerate Mediaset (which controls, inter alia, the main three private free-to-air channels in Italy) for an alleged abuse of dominant position.17 In fact, and contrary to the forecasts made by the Commission, Mediaset was in a position to acquire the broadcasting rights of the main Italian football teams, thereby excluding the incumbent (and near-monopolist) pay-TV operator, Sky Italia. This may go to show that the reality of the sector is more complex and evolves faster than one may infer from the Commission practice, thus putting into question its stance regarding exclusivity. The experience of the evolution of the Italian media sector will be used as the starting point for the evaluation of alternative regulatory options.

The independence of the mass media has been regularly restricted over the past two years in Ukraine. Following a period of relative freedom in 2005–2010, the scope of direct and indirect government control of the press has increased, cancelling out the achievements of the Orange Revolution in this area. The press in Ukraine is less and less able to perform its role as watchdog on the government and politicians and as a reliable source of information on the situation in the country to the public. This is mainly due to: (1) the concentration of the most important mass media in the hands of Ukraine’s most powerful oligarchs, whose business interests depend on the government; (2) the use of the press as instruments in political and business competition; (3) the ruling class’s subordination of the institutions which supervise the press; (4) repression used against media critical of the government and (5) the lack of an independent public broadcasting corporation. As a consequence, the press has hardly any impact on the political processes taking place ahead of the parliamentary election scheduled for 28 October. This is also an effect of a passiveness present in the Ukrainian public, who are tired of politics and are focused on social issues. Cases of abuse or corruption scandals revealed by the press do not provoke any response from the public and are rarely investigated by the public prosecution authorities. The more popular a given medium is, the more strongly it is controlled by the government. At present, television has to be recognised as the least reliable of the mass media. In turn, Internet news journals are characterised by the greatest pluralism but also have more limited accessibility. The political conditions in which the mass media operate in Ukraine lead to various forms of pathology. The most serious of them are censorship by the owners and self-censorship performed by journalists, and a great share of political advertorials. As the parliamentary election is approaching, the pathologies of the Ukrainian media market have been showing up with greater intensity.

The European Commission’s interference through state aid rules with the Member States’ support for public service broadcasting is not undisputed. Member States, public broadcasters and numerous academics fear that State aid control might limit the public service remit and, hence, the multi-platform and holistic role of public broadcasters in the converging media industries. This paper assesses to what extent the fear for Commission intervention is, indeed, justified. It starts with the assumption that the transformation from public service broadcasting to public service media is vital for the European democratic society. The paper leads to the observation that, in fact, European State aid policy might contribute to such a necessary and urgent transformation, instead of threatening it. The paper consists of three main parts. Firstly, the legal constraints and margins of the Community’s State aid framework are discussed. Secondly, the application of the rules to a selection of public broadcasting cases is analyzed. Finally, some conclusions are drawn from the analysis.
