Nickelodeon kids channel is latest to offer Internet-only subscription service

Add Nickelodeon to the list of channels planning a stand-alone Internet offering.

What's not yet known is whether this offering will be the same channel as what cable and satellite TV subscribers now get. Nickelodeon owner Viacom Inc. merely says that the offering will have its own brand name. It's possible the service will have just supplemental content or archives of past shows. Viacom says other details, including the price, will come next month. The service is set to launch in March.

Viacom announced the service Thursday during a conference call to discuss the company's quarterly earnings report. CEO Philippe Dauman says the new service "will target the fast-growing mobile market (and) will be very attractive for parents and children."
