Ted Gioia: How long does pop culture stardom last?
"I’ve long believed that 80 years is a typical span of pop culture fame for superstars. I’m referring to the biggest names—the lesser stars burn out in 80 months or 80 weeks or 80 days. But the top draws retain their fame for the entire lifetime of their youngest fans—and given current life expectancies of the US audience, that can’t be much more than 80 years. We already see the price of Elvis Presley memorabilia starting to drop" - music writer Ted Gioia estimates how long stardom lasts.
