HBO wants to do keep on doing bad things with its current Sunday lineup next summer.

In the channel’s executive session, HBO co-president Richard Plepler and Michael Lombardo, president of its programming group and West Coast operations, officially gave the green light to another season of “Entourage,” a third season of “True Blood” and a sophomore season for “Hung.”

The sheer heat that this summer’s “True Blood”  episodes are putting out makes its renewal a no-brainer.  Ditto for “Entourage,” even if it’s getting a touch long in the tooth by cable TV standards.  But “Hung’s” quick renewal comes as something of a surprise, as it’s barely halfway through its first season.

Could this be a sign that the premium channel is actually thriving in spite of the recession?  Well, Lombardo says, yes. Sort of.

“No business is recession proof,”  he admitted, but described HBO’s business as resilient.  According to Lombardo, they don’t have lots of money to spend, but what he calls an “enviable” amount.  The “cocooning” trend has been good to the channel, according to the execs; DVD sales are doing well, and viewership is up across the board.

“Unfortunately, that has not resulted in the coffers opening wider for original programming,” added Plepler.

But it hasn’t resulted in heartbreaking slices to its content either. “Big Love,” for example,  will be back in January.  The seventh season of  “Curb Your Enthusiasm” is coming September 20, coupled with the arrival of “Bored to Death,” a new comedy starring Jason Schwartzman, Ted Danson and Zach Galifianakis.

HBO was not ready to commit to another season of “The No. 1 Ladies Detective Agency,” but execs advised reporters not to write any eulogies just yet. Their hesitance to renew has more to do with the sudden passing of series creator Anthony Minghella last spring. Minghella sculpted the direction for the first season and directed the pilot before he died, and execs stressed the need to find the right showrunner to take his place before committing to season two.

As for a third season for “Flight of the Conchords,” Lombardo said that’s entirely up to Jemaine Clement and Bret McKenzie. “We’re waiting, and as soon as they tell us they’re ready, we’d be thrilled,” Lombardo says.
