For whatever reason, the Roseanne premiere was a hit in the essential demographic, and the renewal was not a huge surprise.
It is somewhat surprising that Roseanne’s revival premiere performed so well in the key 18-49 demographic.
It should be interesting to see how the ratings for future episodes are different from the premiere.
A decent chunk of that demo wasn’t even born when Roseanne first hit the airwaves in 1988 or even went it went off the airwaves for the first time in 1997.
