When ONdigital launched on 15th November 1998, the BBC provided their Parliament channel as an audio service (as they did at the time on DABdigital radio) with just a blank screen.
After ITVDigital failed, the BBC gained an extra transmission multiplex (B), and when Freeview launched on 30th October 2002, BBC Parliament was upgraded to quarter-screen service, with a very limited text service to provide additional information.
Many viewers have complained about this Freeview service because the channel is difficult to watch and it was not possible to use the subtitles.
The channel's controller, Peter Knowles, said ""No other parliamentary channel in the world matches what BBC Parliament now offers: round the clock broadcasting of Parliament, by digitalterrestrial, cable, satellite and the web. For the first time, the full proceedings of Parliament can be seen on terrestrial television, broadcast as a normal TV channel."
Additionally, programmes that carry subtitles will double to 810 hours a year.
On Freeview the channel has actually shared (on hidden channel 303) with the 2-screen BBC News Interactive, but it remains to see if the interactive news service disappears, or if it is to be expanded to six screens, as per the cable and satelliteservices.
