Why has American pop culture stagnated?

Technology, through the market demand and creative limits it sets, is presented as the root cause of stagnation in American pop culture. Ted Gioia's figures show that only 27% of tracks streamed are new or recent and that 83% of Hollywood revenues come from franchise films. Adam Mastroianni's graph shows movies rose from 25% remakes and sequels to over 80% in about 20 years. Gioia blames social media companies for algorithmic feeds, but the writer argues that market incentives would produce the same result anyway.
