"Parenthood has a new episode average of a 2.63 rating for adults 18-49. It may not look like much, but on NBC it’s the biggest scripted fish they’ve caught all season. NBC has only 3 scripted shows with better new episode averages (Office, 30 Rock and Law & Order: SVU). By comparison, CBS has thirteen scripted shows with a better ratings average.
On CBS, Parenthood would get thrown back in the lake. On NBC, it looks like a trophy".
This is as of April 13th. Most stuff I've been reading about the series says it's not a hit, but likely to be renewed.
