The Act mentions advertising in two respects only:

Advertising of applicaitons for licenses and a total exemption for advertising films. Any other discussion based on advertising - and there has been much on the mudcat over the last few years is solely based on Kim Howell's statements in parliament, which in this respect were never clear and consistent. The contexts in which I recall his use of advertising was mostly likely concerned with advertising with a view to attracting an audience and at least on most occassions a paying audience. But he never said that in so few words.

Most importantly, as Shambles pointed out, those who are sriting about advetising are not writing in about the content of the act.
