摘要：Confronted in different geographies with an identity crisis, public media operators are facing new challenges every day: the distribution of content on different platforms and the development of mobile peripherals. Here is an opportunity for the public service media (PSM) to rediscover their path. In this work, we have developed an analysis to the applications for smartphones from the British broadcaster, BBC, and the Portuguese one, RTP. We tried to comprehend what kinds of contents are presented on the apps for the iPhone and the possibilities created there for the citizens' integration and the distinctive features between RTP and BBC. The adaptation of public service operators to a new digital paradigm is a challenge that will require its reinvention in the context of media convergence, a feat that coincides with other structural changes in several European countries. From a communication made at a national level, through broadcast media such as radio and TV, there is a need and an opportunity to operate on a more global scale, leveraging the potential of digital, which allows publishing content on multiple platforms, targeted to more diverse publics, opening a new set of possibilities for citizens. The work that we present is part of our PhD project that has, as one of its premises, to monitor the adaptation of different media to the emergence of mobile media communication in the information society. var currentpos,timer; function initialize() { timer=setInterval("scrollwindow()",10);} function sc(){clearInterval(timer); }function scrollwindow() { currentpos=document.body.scrollTop; window.scroll(0,++currentpos); if (currentpos != document.body.scrollTop) sc();} document.onmousedown=scdocument.ondblclick=initialize 34 Ivo Neto e Felisbela Lopes From Broadcast to the digital new challenges I n most Western European countries, the Public Service (PS), in the media .HOGZDVERUQZKLOHWKHUDGLRZDVFODLPHGDVWKH.UVWPDVVPHGLXPLQWKH early twentieth century (Moe, 2010). The development of television and its rapid transformation as a means of communication all over the world, forced PS managers to enlarge its diversity and embrace a new set of challenges. With the emergence of computers, and consequently the Internet, the notion of PS and its area of operation have been widely discussed. When we look, in a particularly way, at the development of television, we come to understand the challenges inherent to PS. Some of us can recall when television had only one channel available; others remember a time when there were only PS operators and channels supported by advertisement. There are still people who remember when basic services and paid broadcasting satellite services were available for WKHYHU\.UVWWLPH "Whatever the length of our memories, we are all aware that the number of channels is growing, that the switch to digital broadcasting has added more VHUYLFHV WKDW PDQ\ RI XV DUH VSHQGLQJ VLJQL.FDQW DPRXQWV RI PRQH\ IRU pay services, and that we can now watch streaming television and television programmes on many types of devices" (Picard, 2013: 3). Joaquim Fidalgo also describes the changes that PS has experienced at the end of the last millennium until the present day, in an undertaken research on TV. The researcher from Communication and Society Research Centre, at University of Minho, states that, among other changes, it is possible to prove the emergence of: "(…) new technological possibilities for broadcasting TV (satellite, cable, Internet, broadband) which is no longer dependent on the allocation of a scarce and public airwaves, and that also makes it cheaper to have access to the television activity" (2005: 25).
