The counting of seasons of animated series is always tricky, but Deadline reports that Family Guy (technically currently airing its 10th season) has been renewed for a 11th season. But we already had it renewed for next season, so this renewal takes it beyond the 2012-13 season. Fox has also renewed American Dad for an eighth season. "Dad" is currently airing it sixth season. Look for a press release shortly.
The Cleveland Show -- currently about to finish its third season and already renewed for a fourth -- has not yet been picked up for a fifth season, with Fox waiting to exercise that option.
