In a study by the British public broadcaster, the energy impact of radio broadcasts on all bands was calculated: Medium Waves, FM, DAB and digital terrestrial TV. In addition to the consumption to produce the programs and distribute them on the different platforms, the research also estimated those to listen to them, then linking them (for each medium) with the hours of listening, to quantify the hourly energy consumption. This highlighted the key points where to concentrate efforts to reduce the energy footprint.
BBC radio attracts over 30 million listeners in the UK every week through live stations, podcasts and other on-demand content. Unlike TV, which completed the digital switchover in 2012, the BBC still provides analogue radio services that continue to make up a considerable portion of the audience. While broadcasters are discussing whether radio should switch to digital, the media industry has been studying the possibility of migrating to distribution exclusively over the Internet. Both of these approaches would have inevitable environmental impacts that have yet to be quantified. The research then assesses the effect that a digital radio switchover or a transition to IP-only services could have on energy consumption, and addresses also alternative scenarios.
The famous aggregator will have to turn off more than 90% of the audio streamsit hosts to prevent UK users from listening to foreign broadcasters. It has in fact lost the lawsuit filed in 2017 by Sony and Warner, two big names in the music business (together they control 43% of the global market). The High Court of Justice has recognised that TuneIn has violated the record rights because it is not a simple intermediary (which publishes only the links) but also inserts advertising. In the UK, therefore, those who want to listen to a foreign broadcaster will have to search the web for the address of the radio and streaming site (or change aggregator). The ruling protects radio stations (TuneIn places advertisements into their programming) and other countries may comply with the decision of the English High Court. But in perspective it calls into question one of the pillars of the web: the ability to listen to radio stations around the world. So far, record companies have considered foreign listeners to be marginal to the web, but now music could change.
