(Bloomberg) Dish Network unveiled the first major Internet-streaming television service from a cable or satellite company, a $20-a-month set of 12 channels that targets U.S. customers who don’t want to pay for larger, more expensive TV packages. Called Sling TV, the service offers live feeds of sports, news and scripted shows on TVs, computers and mobile devices and will start later this month, Dish announced Monday at the Consumer Electronics Show in Las Vegas. Live channels include ESPN, TNT, CNN, TBS, HGTV, Cartoon Network and Disney Channel. The package doesn’t include a single broadcast network or the most-watched cable news channel, Fox News. Pay-TV companies experiencing little or no subscriber growth are being forced to offer products not tied to the traditional TV bundle. Netflix Inc. has more customers than any single cable or satellite operator, with 37 million U.S. subscribers for an on-demand streaming video service that costs $8.99 a month.
