I think perhaps this is partly because of our age, but mostly because of the media world we live in. With fewer channels on the tv and only live broadcasting, more people watched the same. Nowadays, we can pick and choose, meaning that I don't know anything about most "influencers" (which is a horrible word, worthy of its own grinding my gears post) or musicians performing in genres I don't listen to. Most tv shows with "celebrity specials" star people I've never heard of.
