Interactive Television. Please help!

Who uses interactive television? I’m about to undertake a project on this and I was wondering if you guys could help me out please?

All i want to know is your views on interactive television, any ideas how it could be improved and reasons what it could be used for and mainly why does it need improving.
Any posts I’m sure will be helpful. Please help,


by the lack of responses I think you can gather that interactive TV needs to develope reasons for someone to use it. I’m not sure what it can do that watching TV and surfing on a laptop with a wireless network can’t, while the former can do a lot that ITV can not.
