Re TV I can see where you're both coming from : yes we have a milion channels with theoretical niches for everyone, but in practice (what was saying) tehre's a cross cultural homogenised blandness : 1000 channels al showing re runs of Friends and will and Grace.

But I was really meaning the Internet - where a genuine every-niche exploitation/heterogeneity has taken place - my stock example being that if you now want to find pages for men who fantasise about being swallowed by giant women, well, you can :-) (Or just spend a week reading every link on Boing-Boing.)
