That'd make sense if the regional ancillary service disappeared during GMTV's hours, but they didn't (at least not in Central nor in Yorkshire by the sounds of things).

I suspect that either the whole thing was added locally when the news was, and each region did something to switch between presenting as their own service or GMTV Text + redressing page 600. Unless it would have been possible for GMTV to emit a single page ancillary service on Page 600 and for the region to add the rest of the range?

It could be that the service changed in each region at 6am, after all GMTVs and almost all the regions (I think Westcountry was the exception) were done by Intelfax.

It sounds like it changed - the early days it was a seperate service for GMTV and later on it was mixed? The mixed version with GMTV and the regional pages would have been just Intelfax creating each regional version with GMTV pages that were the same on each

A quick look at The Teletext Archive and yes there were some GMTV pages were on p640 in Central in the evenings but of course it's difficult to see what actually went out between 6 and 9:25 unless there's a capture from that time slot. I imagine even if the pages were the same the header will have changed
