HBO continues to explore the broadband video waters via a deal with YouTube to launch a branded HBO channel starting today.

The channel will include videos from HBO shows including “Flight of the Conchords,” “The Wire,” “Def Comedy Jam,” “Real Time With Bill Maher,” “Real Sports,” “Extras,” ”Stand Up Comedy,” “Habla y Habla” and “Entourage.” Also on offer are full-length episodes of the network’s latest original series, “In Treatment.”

The deal is strictly promotional and will not include advertising, HBO said.

“We invest significantly in developing HBO programs and are always searching for new promotional platforms,” said Joseph Giraldi, HBO’s director of digital distribution and partnerships, in a statement.
