AT&T’s pending over-the-top service DirecTV Now continues to add content partners, signing a carriage agreement with Viacom that will include a dozen of the programmer’s cable networks including MTV, Comedy Central and VH1.

Terms of the deal were not disclosed. Other Viacom networks included in the agreement are CMT, Logo, BET, Nickelodeon, Nick at Nite, Nick Jr., Spike, TV Land and Viva.

The deal is the latest in a flurry of agreements AT&T has made for DirecTV Now in the last few months. In September alone it has reached deals with NBC Universal, Discovery Communications, Scripps Networks, A+E Networks and Turner. The DirecTV Now service plans to have more than 100 channels of live and on demand content at launch.

“Viacom’s audiences are among the most sophisticated and enthusiastic consumers of programming on digital platforms, both at home and on the go,” said Viacom executive vice president, Global Content Distribution Denise Denson in a statement. “We are committed to delivering the highest-quality content wherever and whenever our fans choose to enjoy it, and are excited to be launching a broad portfolio of our popular networks on DirecTV Now.”

For Viacom, the carriage deal comes on the heels of recent management turmoil at the company and talk that it may merge with former corporate sister CBS.

“The diversity of content makes Viacom Networks’ programming a great fit for our DirecTV Now streaming service,” said AT&T chief content officer Dan York in a statement. “With DirecTV Now, we’re focused on offering quality content with the freedom to watch it anywhere anytime. Viacom is a welcome addition.”
