It's been almost a decade since 16 and Pregnant debuted to harsh criticism and stellar ratings.
In the years since, the show has taken on a life of its own, making stars of its original cast members and spawning numerous spinoffs.
There have been a lot of surprises along the way -- who would have thought the ladies of Teen Mom 2 would prove to be a bigger hit than the OGs? -- but the biggest surprise of all is how popular the franchise remains.
So take a trip down Teen Mom memory lane with this rundown of every spinoff launched by 16 and Pregnant.
It's quite a list:
16 and Pregnant
It all started with 16 and Pregnant, which made its debut on MTV way back in June of 2009.
Moving Up to the Majors
Unfortunately, most of the girls featured on 16 and Pregnant did not go on to Teen Mom fame. Some were never re-cast, while others -- such as Mackenzie McKee -- starred on spinoffs that didn't last.
Cause For Optimism?
The casting of Briana DeJesus on Teen Mom 2 offered some hope to former 16 and Pregnant stars, and no doubt many were optimistic that they too would get the call from MTV.
Unfortunately, the last time producers had a vacancy to fill, they went outside the franchise, adding Bristol Palin and Cheyenne Floyd.
Teen Mom OG
Of course, many fans of the franchise were upset by the fact that Bristol and Cheyenne did not meet the core criteria of the show in that they were not "original girls" featured in the first season of 16 and Pregnant.
Amber Portwood, Farrah Abraham, Maci Bookout, and Catelynn Lowell were the first stars of the show that started out as Teen Mom and became Teen Mom OG.
