Scroll down to see nine TV series that didn’t just spin off but spun gold.
‘The Andy Griffith Show’
This 1960s sitcom, starring the titular comedian as Mayberry sheriff Andy Taylor, won six Emmys during its run and made many “Best Of All Time” lists since—though its mothership series, The Danny Thomas Show, was no slouch either.
With 35 seasons over the past 20-plus years, this MTV reality competition has outshone its two predecessors, surpassing The Real World and far surpassing Road Rules.
This CBS “action-comedy-mystery-medical-crime drama,” starring Dick Van Dyke as Dr. Mark Sloan (no relation to Grey’s Anatomy‘s McSteamy), lasted much longer than the CBS crime drama from which it was spun off, the questionably-titled Jake and the Fatman.
The second installment in The CW’s Arrowverse—starring Grant Gustin as the speedy superhero—has outstripped the originator, with almost every season averaging more viewers than its equivalent Arrow season.
‘Law & Order: Special Victims Unit’
No American primetime drama has aired more seasons than this Mariska Hargitay-led NBC procedural, not even the wildly-successful original Law & Order.
With 31 seasons and nearly 700 episodes, this Fox animated hit is currently the longest-running primetime show in the history of American television, but don’t forget: It got its start as a series of shorts on The Tracey Ullman Show.
‘Teen Mom 2’
The MTV reality show 16 and Pregnant lasted five seasons, but its spinoffs Teen Mom and Teen Mom 2 have both stuck around longer. In fact, the latter series has aired nine seasons and 171 episodes to date.
