Teased earlier this year by the CEO of CBS, the higher-priced tier will strip out ads from most of its on-demand library.
The ad-free tier of CBS All Access will strip out commercials from most of its on-demand library.
CBS launched a $9.99-a-month, ad-free subscription Wednesday for its online streaming service, CBS All Access.
The higher-priced option joins its standard tier that costs $5.99 a month, which will remain unchanged.
There is one caveat: All Access can't strip out ads from programs streamed live from local CBS TV stations. In addition, "select on-demand shows will include promotional interruptions," the company said in a statement.
The service's on-demand library includes full seasons of many past and current CBS shows as well as upcoming original series, such as a "Star Trek" TV reboot and a spinoff of "The Good Wife." (Editors' note: CNET is owned by CBS.)
CBS CEO Les Moonves said in February the company was contemplating the ad-free offering for All Access.
