Well, this is good news for Apple's iTunes service (and perhaps a revamped Apple TV, when it happens): nearly half (46%) of 18- to 25-year-olds spend as much time using online video services as they do watching TV, says RealNetworks.

Research by online video software firm revealed that just under a third (32%) say the computer is their preferred platform for watching TV and video. However, when it comes to 36- to 45-year-olds, 20% watch at least 50% of TV programs and movies via a computer.

"It's still early days for online video but as each year passes the quality and breadth of online video content increases dramatically and the tools to access, manage, share and consume the content grow ever more sophisticated," says Marili 't Hooft-Bolle from RealNetworks.
