Family Guy Beavis and Butthead Crossover and Boy Bands

Boy Bands are a thing of the 1990s. Sure there were The Beatles or The Monkeys cherished by the female teenage audience, but with the 1990s I felt there was an abundance of Boy Groups like Take That, Boyz 2 Men and others. And because Beavis & Butt-Head, as well as Family Guy, aired their respective pilots in the 1990s I wonder why they rarely or never (I don't remember any episodes focused on Boy Bands) made fun of these teen idols, until the crossover happened in this video in the 2020s. Anyone has any idea why there was never any shows focusing on Boy Bands in the 90s or early 2000s? Or did I miss them? Then please name the title.
