There is loads of crap on TV, sure, but it's not "full" of it... nor is it all just celebrity nonentities. It doesn't take much to pick out the gems on TV, and they are there to be had.
Magazines though - I once worked out we only actually need about 15 magazines. It's ridiculous that you walk into Smith's and the magazine section extends into the distance, straddling several time zones. 95% of it is crap. Of course, getting rid of them would release onto the job market all those people with names like Clare, Claire, Emma, Natasha, Sara, Lara, Kara, Tara, Veruca, Parabola, Justin, Ben, Ben, James and Ben, whose otherwise pointless media studies degrees render them useless for anything other than churning out lame magazines. So we'd have to find something for them to do.
