Broadcast Is an Important Part of ICT - and of Green ICT!
The "C" in ICT stands for "communications" and broadcast is a significant component of that industry and technology segment. Consider the statistics.
At the core (facilities) level are 27,000+ television stations and 44,000+ radio stations. Add to this 10s of thousands more studios, postproduction companies and other industry facilities, all loaded with analog and digital media equipment.
At the communications layer, each of those television and radio stations have a transmitter. Add to that 62,000+ television repeaters and countless radio repeaters. And don't forget the tens of thousands of cable systems around the world distributing signals on copper and fiber. The United States alone has 5,200+ cable (CATV) systems.
Finally, the edge is populated with 1.7 billion televisions and 4 billion radios. The media infrastructure also services the ~4 billion mobile connections that can potentially receive audio/video content.
Many populous areas have yet to fully convert to DTV. Some of these areas and their DTV conversion completion dates are: China 2016, Brazil 2018, Indonesia and Russia 2019 and Hong Kong 2020. This means that many of televisions are still analog units and will likely be e-waste by 2020. The United states completed its conversion in 2009 and there are still tens of millions of sets in US households. (More on DTV and e-waste)
