BEIJING, March 2 (Xinhuanet) -- U.S. cell phone users in 20 states can now view full-length television programs with picture quality similar to regular TV for 15 U.S. dollars a month thanks to Verizon Wireless.

    America's second-largest cell phone provider on Thursday announced it has launched the country's first commercial mobile television service.

    The venture of Verizon Communications Inc. and Vodafone Group Plc will utilize a service developed by Qualcomm Inc. unit MediaFlo and includes eight channels broadcasting full-length TV shows to phones 24 hours a day.

    Cell phone video services, first launched in the U.S. in 2004, have only about 7 million customers out of about 232 million cell phone subscriptions, according to Ovum analyst Roger Entner, who said higher-quality pictures could change that.

    "I think the impact in the beginning will be modest," since Verizon is rolling out the service gradually, said Entner. But he estimated MediaFlo users could increase to 20 million to 30 million people within about seven years.

    The picture quality of the new service will be on a par with home TV and about twice as clear as Verizon Wireless's existing Vcast video service, spokesman Jeffrey Nelson said.

    AT&T Inc.'s Cingular Wireless, the biggest U.S. cell phone service in terms of subscribers, has said it plans to launch MediaFlo to its customers later in the year.

    The first phone to support MediaFlo, the U620 from Samsung Electronics Co., is being sold for 199 dollars, or 149.99 dollars for customers who sign a two-year contract. Verizon plans to add an LG Electronics Inc. phone in weeks.

    Subscribers who also sign up for cell phone Internet access, for 5 dollars a month, and Verizon's existing Vcast service, which lets users download short video clips for 15 dollars a month, can add MediaFlo for 25 dollars a month, or 10 dollars less than if they were to buy the three separately.

    Entner said adding eight channels for another 5 dollars could be attractive for existing Vcast and Web subscribers.

    The MediaFlo service became available on Thursday in cities such as Chicago; New Orleans; Portland, Oregon; Seattle; Las Vegas; Tucson, Arizona; Kansas City; Dallas-Forth Worth; and Salt Lake City.

    Available channels include a live feed from MTV and programming from CBS Corp., NBC, ESPN, Fox, Nickelodeon and Comedy Central. Some programs are shown at the same time as regular TV, while others are rescheduled to match the heaviest cell phone television viewing times, Nelson said.

    Viacom Inc. owns MTV, Comedy Central and Nickelodeon. General Electric Co. controls NBC. Walt Disney Co. owns ESPN.

    Wireless chipmaker Qualcomm plans to build a nationwide network for delivering television to cell phones to kick-start the market. In that way, established operators such as Verizon can offer additional media services to customers without clogging up their own networks.

    Modeo, a unit of Crown Castle International Corp., is also building a network dedicated to cell phone television, but it has yet to name any customers for its service, currently in trial in New York.
