Viacom will make its networks available on Sony's planned internet-based TV service, the companies announced on Wednesday.

Sony will carry 22 Viacom networks at the start, including MTV, Nickelodeon and Comedy Central.

This is the first deal Viacom has struck to provide its networks for a cloud-based TV service, which would compete with pay-TV providers such as cable and satellite companies.

As part of the deal, subscribers to Sony's service will be able to access both live and on-demand content. Financial terms of the deal were not disclosed.

Several companies have pursued similar services but gotten hung up on the details. Intel has abandoned an effort to delivery so called "over-the-top" pay TV that it once expected to introduce last year. The official word on the Viacom-Sony deal comes a year after reports first surfaced of a tentative deal.

Sony previously said it will begin testing the over-the-top service this year on PlayStation consoles and other Sony devices. The company said it will announce additional details about the service in the near future.

Dish Network is also in the process of creating its own internet-based TV service, and has announced programming agreements with Walt Disney and A&E Networks.
