BBC Three will be launched when the government give the BBC approval to launch it. Originally, the BBC submitted plans to the Culture Secretary Tessa Jowell, who has the final say when the BBC wants to launch new or rebranded channels, and she approved plans for BBC Five Live Xtra, Radio 1 Xtra, BBC 6 Music, the CBBC and CBeebies channels for kids and BBC Four but not BBC Three. She didn't like some of what the BBC wanted it to do and told them to think about it and re-submit it later in the year. So the BBC launched BBC Four on top of BBC Knowedge and let a big gap where BBC Three will eventually be.
