AKB48 Nemousu Terebi is another one of their shows. Season two is airing this period, we're already up to episode 6.
Each episode they have to do a challenge of some sort, i.e. making fans in France, make an anime, etc. It's 12 episodes per season.
Season 1 wasn't that great from what I can remember, but season 2 has been fun so far. Especially because I appear in episode 3
