The new season of The Sopranos opens on Sunday, bringing the world of Tony and Carmela, Christopher and Paulie Walnuts back to dens around the country. The show's last previous episode aired in the summer of 2004.

A new sitcom premieres on ABC Tuesday that blends scripted stories with improv. Sons and Daughters was created by Fred Goss and Nick Holly; its executive producers include Lorne Michaels, of Saturday Night Live fame.

It's mid-season in the world of television, and that means some are being cancelled -- or simply phased out.
