Latest TV audience share figures from Britain's Independent Television Commission show the gap between terrestrial giants BBC1 and ITV1 narrowing.

For the twelve months to the end of September, ITV1 -- flagship channel of commercial network ITV -- polled a 24% share, the same as in the last report (covering the year to June).

However, the BBC's leading channel saw its share slip from 26.3% in the last ITC study to 26.1%. The publicly funded broadcaster's second station, BBC2, was also down, slipping from 11.3% to 11.2%.

Of the other terrestrial broadcasters, Channel 4 fell from 9.6% to 9.5%, while Five remained on 6.4%.

The failure of any terrestrial channel to post a rise in audience share in part reflects the migration of viewers to multichannel TV. Nevertheless, Sky One -- the biggest non-terrestrial station -- was also down, falling from 1.7% to 1.6%.
