More choice is on the way for television viewers beyond paying for traditional cable and satellite packages.

Viacom, the parent of MTV, Nickelodeon and Comedy Central, announced on Wednesday that it had reached a deal with Sony to make 22 of its networks available via a new Internet-based television service.

Scheduled to start later this year, the service is expected to bring live TV and on-demand programming to Sony’s network of 75 million Internet-enabled Sony devices in the United States, including PlayStation game consoles and web-connected televisions.

The deal is the first time that Viacom has made its networks available to an Internet-based live and video on-demand television service. Beyond Viacom, the service is expected to include content from other major network groups. Sony has held talks with Discovery Communications, Time Warner and Starz, among others, about including their networks in the new service, according to people with knowledge of the discussions who spoke on the condition of anonymity.
