You mean like how the blockbuster movie industry is in a crisis because most people prefer watching VHS of movies from the 1980s rather than watching the latest Marvel movie?
That doesn't happen, that's not how any cultural medium works. Enthusiasts keeping old stuff running are a minority. Also they are likely to consume a lot, give them a new take on what they like and they'll gladly try it... If it's good enough.
Of course, that's the real problem. Some companies dream of wiping out everything that came before so their newest enshittified predatory crap doesn't suffer from the comparison.
