BBC Online, formerly known as BBCi, is the BBC's online service. It is a large network of websites including such high-profile sites as BBC News and Sport, the on-demand video and radio services co-branded BBC iPlayer, the children's sites CBBC and CBeebies, and learning services such as Bitesize. The BBC has had an online presence supporting its TV and radio programmes and web-only initiatives since 1994 but did not launch officially until December 1997, following government approval to fund it by TV licence fee revenue as a service in its own right. Throughout its short history, the online plans of the BBC have been subject to harassment from its commercial rivals, which has resulted in various public consultations and government reviews to investigate their claims that its large presence and public funding distorts the UK market.
