You can see this in football. In the U.K. satelite TV massively increased the market - no longer were people spending £30 a game to watch at a stadium with a capacity of 30k, they were spending £10 a game to watch on tv with a capacity of millions.

This extra cash poured into the salaries of the footballers in the top division, salary’s doubling every 4 or so years for a sustained period.

The money didn’t trickle down to lower divisions or youth training or on site staff.
