CBS is going to start offering a new stand-alone service.

CBS All Access, which will cost $5.99 a month, will have full seasons of past CBS daytime and primetime shows. CBS made the announcement the day after HBO said it would offer HBO Go as a stand-alone service.

"CBS All Access is another key step in the Company's long-standing strategy of monetizing our local and national content in the ways that viewers want it," said Leslie Moonves, the CBS chief. "This new subscription service will deliver the most of CBS to our biggest fans while being additive to the overall ecosystem. Across the board, we continue to capitalize on technological advances that help consumers engage with our world-class programming, and we look forward to serving our viewers in this new and exciting way."

A CBS spokesperson said that CBS is not free as it is. Cable, satellite and telco bills include a fee for the channel.

CBS All Access will still have commercials, but it will have less commercials than what's on TV. And shows that are on air won't be available until the next day.

The new stand-alone service is already available, and there are episodes for 15 episodes of current shows and as well as 5,000 episodes from the CBS library. Shows like "Star Trek," "Cheers" and "Twin Peaks." Current shows' seasons won't be fully available.

"Our focus is to develop that best cross-platform video experience possible," said Jim Lanzone, CBS' Interactive president. "We want our audiences to be able to watch CBS's industry-leading content live and on demand whenever and wherever they want. CBS All Access delivers on that promise by giving our audience not only more CBS content, but also more ways to watch in a seamless user experience."
