After 1993 the ITV companies got responsibility for subtitling and the 600 magazine (the 'Ancillary Teletext Service) which could only be TV related content. That was originated at the ITV company. Channel 4 had the same but the 400 magazine, and Channel 5 with 500
Meanwhile Teletext Ltd also provided local content but it all came from them and their providers. They were more local than ITV, as their service originated at the transmitter sites and they could potentially broadcast 25 different teletext services on both ITV and Channel 4.
