There was Sky Sports Active as well of course. I remember being really excited about it coming and annoyed that our Amstrad Digibox took a while to get the update to actually use it a couple of weeks after launch.
In the end it was gimmicky really, only useful in my view in the following ways:
*Highlights during the football if you missed anything
*Fanzone was sometimes entertaining and I think lasted even after Active ended
*Being able to see the cricket score cards, runrates and various statistics on demand was a nice feature too.
Some videos of it:
Sky News Interactive I miss just for allowing viewers to stay with a press conference, event or Parliament after the main Sky News had cut away from it.
