ITV will increase the investment in its multichannel ITV2 from £40m a year to nearly £60m.
ITV digital channels programme director Steven Andrew said the extra money in 2007 would see commissioning in drama, comedy and factual entertainment genres, according to Broadcast.
"The message is you ain't seen nothing yet. We have big ambitions for ITV2," he said.
He continued that ITV2 is in a strong position to launch high profile new series, because it is beginning to beat Channel 4 and Five in the targeted 16 to 34-year-old demographic on strong nights.
ITV2 controller Zai Bennett said the upcoming winter season would be the first to showcase the channel's "fresh approach" to programming. "We want our shows to be celebratory in tone, not cynical or downbeat," he said.
Local productions to be launched include sketch series Comedy Cuts (ITV Productions).
