Channel 4 Teletext
The main operator of the Channel 4 teletext service matched that of ITV, originally being Oracle before switching to Teletext Ltd from 1993. However it differed in the content offered, with both teletext providers splitting their pages between the two channels and cross-promoting them where appropriate.
An ancillary service, known for most of its lifetime as 4-Tel was also provided. Similar to most of the ITV services, this service was produced for many years by Intelfax and designed to give supplemental information around the Channel 4 programmes in those pre-internet days.
Teletext on 4 (Midlands) - 20/2/1994
A 1994 service from Teletext Ltd, still under the 'Teletext on 4' branding at this point. Officially it's from the Midlands region, although the importance of the regional service on 4 was less prominent than on 3, mainly affecting things like show and cinema listings. The Winter Olympics are in full swing at this point, so a lot of pages are dedicated to this. Meanwhile Digitiser is taking a look at Amiga Public Domain software, and full motion interactive movies on the Mega CD. In the 300s, the Intelfax-produced Ancillary service '4-Tel' for Channel 4 can also be found, providing important backup information for shows on the channel.
Teletext (North East) - 6/9/1997
Channel 4's Teletext service from the day of Diana's funeral, 6th September 1997. As well as additions to many pages mentioning disruption is to be expected due to the funeral, the entire racing service has been suspended with many bookmakers' pages being replaced by messages of condolence. A small selection of pages from across the service, although no 4-Tel pages present in this sequence unfortunately due to a poor quality recording.
