HBO has canceled Hung, How to Make It In America, Bored to Death and renewed Enlightened.

Hung and Bored will end after three seasons and America after two, the network said. The shows failed to capture the audience and buzz of acclaimed HBO shows including Game of Thrones, Boardwalk Empire, and Curb Your Enthusiasm.

The cancellations dramatically change the lineup of the network, which will debut six new shows next year: the Dustin Hoffman horseracing drama Luck, an untitled Aaron Sorkin series, Ricky Gervais' Life's Too Short, as well as Veep, Girls, and Angry Boys.

Thrones and Boardwalk will return, along with True Blood and Treme. There is no announcement yet on the future of Curb Your Enthusiasm -- creator Larry David tends to decide season-by-season whether he wants to continue.

Hung starred Thomas Jane as a male prostitute, and Bored followed Ted Danson, Jason Schwartzman and Zach Galifianakis. (Danson recently became the lead actor on CSI, in addition to frequent appearances on Curb; the cancellation slightly cuts down on his heavy workload.)

America, about twentysomethings starting out in New York City, followed an ensemble cast of young actors.

The next season of Enlighted will be its second. The series has earned Golden Globe nominations in the Best Television Series -- Comedy or Musical category and in Best Performance by an Actress in a Television Series -- Comedy or Musical for Laura Dern.
