Doctor Who executive producer Russell T Davies says the show will be back for a fourth series (that's British for season). He made remarks at the London premiere of series three.What's less clear at the moment is who will be playing the Doctor in series four. Current Doctor David Tennant has remained silent on the issue. Series three has actress Freema Agyeman playing Martha Jones, the doctor's new assistant. She fills the void left by Billie Piper's departure from the program.
It had been widely suspected that a fourth season was already on deck, but Davies' confirmation should come as good news for Doctor Who fans. Now if only Americans didn't have to wait months or years for each new season to show up on the SciFi channel.
The BBC plans to set up three YouTube channels that will feature short clips of BBC content. Two channels will be focused on entertainment, while one will be a news channel.
