The Internet is taking an increasing amount of people's time and, in fact, given that they're spending more time on Internet, advertising hasn't caught up yet.

But it's not clear that TV is going to completely stop growing either. That's not the evidence.

The ads on ... so far, have been often annoying little pop-ups, haven't they? They sort of get in the way and you immediately click and get rid of them.

Is it a generational thing? Do you think that younger people who spend much more time on line than perhaps I do or you do respond to that advertising more than they do television advertising?

Well, in fact, younger peope have always spent less time watching TV than the average and that's actually no, no, ... it's as true today as it's always been. But obviously the spend more time on line because on line wasn't available.

The thing that's really taken off in on-line world is the availability of broadband, which means you can get richer media experiences and it's more pleasurable viewing as opposed to an annoying banner or pop-up ad.

But there's no evidence yet that children that spend more time away from TV don't then take up TV when they've got families and are slightly busier although that is what some people believe.

Now, are we getting closer, or are those people whose livings depend on this, getting closer to the Holy Grail, which is what people watch, what they want to watch and where they want to watch it? Or is the market so diverse that it's confusing everybody, not least the advertisers?

I think they're both ... Ironically, I think both are true. At the moment, there are lots of different offers which are very, very diverse and confusing.

Some people who want to watch when they want to, that's becoming more available. So Video-on-demand, Google TV will presumably offer great TV through Google TV search and navigation, but there's still a big market for schedulled TV, and that's, in fact, the people that still continue to watch ITV and they're not gonna stop in the next four, five years.

Theresa Wise, thanks very much for joining us.

Thank you.
