What's good about it?
- There are hundreds of channels
- There are lots of interactive services giving extra video eg. Sky Sports Active
What's bad about it?
- It's expensive if you want all the movie and sports channels: it's about £400 a year
- It can send a lot of information out, but you can't send much back. So it's difficult for it to be really interactive which means you can't have things like messageboards
