In other words, all they were doing was switching the output from the regional companies news studios to the main suites. What would've happened at weekends, when GMTV didn't have regional news?

This leads to another question; had Oracle retained the teletext franchise beyond 1992, would this have meant their regional sections being available during GMTV? On the flipside, had TV-am remained on air after 1992, and Teletext UK had the teletext service, I guess the regional teletext sections wouldn't have been available during TV-am?

I imagine at weekends the same happened, just with no bulletins. The regional companies were taken out of the chain totally during those times, it just passed through their buildings 

If TVam had stayed but Teletext Ltd had still git the license then there'd have been no difference during TVam. Teletext was inserted into the VBI at the transmitter sites so the difference in who was supplying the video was irrelevant. 

There woukd hav been a TVam ancillary text service on p600 of course
