BBC iPlayer, commonly shortened to iPlayer, is an internet television and radio service and software application, developed by the BBC to extend its former RealPlayer-based and other streamed video clip content to include whole TV shows.

BBC Redux was developed as a proof of concept for a cross-platform, Flash video-based streaming system. BBC iPlayer left beta and went live on 25 December 2007. On 25 June 2008, a new-look iPlayer was launched, originally as a beta-test version alongside the earlier version. The site tagline was "Catch up on the last 7 days of BBC TV & Radio", reflecting that programmes were unavailable on iPlayer after this time (with some exceptions). The BBC state on their website that this is due to copyright reasons. The marketing slogan was later changed to "Making the unmissable, unmissable". In May 2010 the site was updated again, to include a recommendations feature and a "social makeover".

In February 2011, the BBC iPlayer was once again modified to include links to programmes from other broadcasters, including; ITV1, ITV2, ITV3, ITV4, Channel 4, E4, More 4, Film 4, Channel 5, 5*, 5USA and S4C. The feature was added to the search function and the channels function. When a user clicks on a programme by another broadcaster, they are redirected to the relevant broadcaster's catch up service (either the ITV Player, 4OD or Demand 5).

Ronald Antonio "Ronnie" O'Sullivan (born 5 December 1975) is an English professional snooker player known for his rapid playing style, and is nicknamed "The Rocket". He has been World Champion on four occasions (2001, 2004, 2008 and 2012) and, with career earnings of over £6 million is second after Stephen Hendry on snooker's all-time prize-money list. O'Sullivan has been the world's no. 1 player on five occasions, and has won a total of 24 ranking titles. He is second, again behind Hendry, on the list of players making the most competitive century breaks, with a total of 678. O'Sullivan has compiled 11 maximum breaks in professional competition, a record which he shares with Hendry. He also holds the record for the fastest maximum break, at 5 minutes 20 seconds.

O'Sullivan is considered by many fans, critics and professionals, including fellow multiple-World Championship winners Hendry and Steve Davis, as the most naturally talented player in the history of the game. He has, however, been involved in a number of controversial incidents during his career.
