Hulu is getting classic CBS shows such as "I Love Lucy." (CBS )

CBS has struck a deal to put much of its vast television library on Hulu, the popular online video site.

The agreement, which takes effect in January 2013, is non-exclusive and is only for Hulu Plus, the platform's subscription service.

Shows that will be available to Hulu Plus subscribers are primarily from the CBS corporate library, and include classic TV shows such as "Star Trek," "I Love Lucy" and "The Twilight Zone," and newer shows including "Numb3rs" and "CSI Miami."

“This marks another agreement that meets the growing demand for our content on new platforms while establishing other incremental ways to get paid for our library,” said Scott Koondel, CBS' senior vice president of corporate licensing.

Such deals have become quite common in the media industry. Movie studios and television production companies have found eager buyers for their content in the form of online video services.
