Why is it so hard to find audio or video of people speaking dialects?

If you listen to local radio shows, all the presenters just speak in the Tokyo dialect. If you search the internet for videos, about all you find is clips of shitty TV shows where dumb assholes from Tokyo go to some rural area and ask people to read words so they can laugh at them when they say them differently. In the rare cases where someone speaks a dialect in an anime or something, most of the time the character isn't very prominent and/or only speaks their dialect on rare occasions (e.g. for about 2 lines when they get flustered before promptly returning to the Yamanote Tokyo dialect).

Where are all the Sean Beans and Michael Caines of Japan?
