Thats definitely what's happening, at least with music. When radio was dominant, the "hot 100" lists were pretty diverse because everyone was exposed to the same set of ~70-150 hit songs every year, that were curated by record companies and radio stations. This system let weirder or more ambitious music occasionally trickle to the top. Without everyone listening to the same programming, the only artists that can be the most popular are the most widely appealing musicians.
