 Many providers of Internet television services exist—including conventional television stations that have taken advantage of the Internet as a way to continue showing television shows after they have been broadcast, often advertised as "on-demand" and "catch-up" services.Today, almost every major broadcaster around the world is operating an Internet television platform.Examples include the BBC, which introduced the BBC iPlayer on 25 June 2008 as an extension to its "RadioPlayer" and already existing streamed video-clip content, and Channel 4 that launched 4oD ("4 on Demand") (now All 4) in November 2006 allowing users to watch recently shown content.
