'Press Red' during ads on Freeview

I noticed during a break on House of Horrors this evening on ITV1 that you could press red during the T-Mobile ad to bring up an mheg page of information.

I know that it's been possible on Sky for some time, but when did this start happening on Freeview?

There's an ad for some Chrysler MPV that has a "Press Red" message appear on screen during part of the ad and it looks like the graphic was added during the ad's production instead of flashing up when the ad begins.

A bit misleading for those who do not have Sky Digital - it doesn't work on Freeview.

Perhaps it's for analogue viewers - press red now to make this ad go away.

Is Chrysler just lasy as its shown on anoluge tv aswell

Red being the colour of most people's On/off buttons!
