==Teletext services==

===4-Tel/FourText===
Channel 4 originally licensed an ancillary teletext service to provide schedules, programme information and features. The original service was called 4-Tel, and was produced by Intelfax, a company set up especially for the purpose. It was carried in the 400s on [[ORACLE (teletext)|Oracle]].<ref name="4Tel">{{cite web|url=http://teletext.mb21.co.uk/gallery/ancillary/c4-s4c/index.shtml|title=Ancillary Teletext Services|access-date=10 June 2007|last=Brown|first=Mike|publisher=MB21|archive-date=2 August 2016|archive-url=https://web.archive.org/web/20160802142356/http://www.teletext.mb21.co.uk/gallery/ancillary/c4-s4c/index.shtml|url-status=live}}</ref> In 1993, with Oracle losing its franchise to [[Teletext Ltd]], 4-Tel found a new home in the 300s, and had its name shown in the header row.
