That will bring the dysfunctional family of "Shameless" back for a fifth season, and the crack team of management consultants in "House of Lies" back for a fourth season on the premium cable network. Each will consist of 12 episodes that will roll out in 2015.
Currently in its fourth season, "Shameless" is averaging 5.5 million viewers across multiple platforms -- up 8% from its previous season. The dramedy, starring William H. Macy as an alcoholic father, delivered its highest-rated episode of its fourth season on Jan. 26, with 1.83 million viewers in its 9 p.m. slot.
"House of Lies" is averaging 3 million viewers a week. It's headliner, Don Cheadle, has brought in bragging rights in the form of awards love -- earning two Emmy and two Golden Globe nominations (taking home a Globe in 2012).
News of the shows' return means Showtime's Sunday programming block remains in place, with "Episodes," previously renewed, also returning in 2015.
