Diet Pepsi will meet you at the Peach Pit

90210 So Diet Pepsi is using characters from Beverly Hills 90210 to illustrate how people prefer it to Diet Coke. But why? Not only is this a forced regurgitation of pop culture, it isn’t even current pop culture. 90210 went off the air seven years ago in a freefall after everyone who made the show popular jumped ship. Maybe I’m being too mean. Yes, the ad ridicules 90210. But even that strategy feels stale. And surely it isn’t time yet for a ’90s pop-culture revival. Maybe the guilty parties here got into Lindsay Lohan’s Panamanian Fairy Dust before putting pen to paper.
