The quote “15minutes of fame” is about the short-lived media publicity or the celebrity of an individual or phenomenon. The expression was coined by Andy Warhol, who said in 1968 that: “In the future, everyone will be world-famous for 15 minutes.” Unfortunately, that has evolved into daily fame for many people that, frankly, is bad for public consumption.
