It looks like MTV has another hit on its hands!
That makes it MTV's biggest new series launch in three years and second biggest in total viewers.
It also ranks as one of the top five new unscripted cable launches of 2017.
It looks like the show also kept those who tuned in. The second part of the two-hour premiere retained 93 percent of its viewers and maintained a 0.87 rating in the same demographic group.
The return of Teen Mom OG right before the Floribama Shore premiere couldn't have hurt. The show began with a 1.25 rating among that demographics group, which is a 19 percent increase from last season's average.
Nielsen says that's the biggest Teen Mom debut in three seasons.
