(written from a Production point of view)
CBS Consumer Products, Inc. is the licensing and merchandising unit of CBS Entertainment which manages the licensing of products for the various television shows owned by CBS, CBS Television Studios and CBS Television Distribution.
The company also collaborated with Mad Science to develop Star Trek Live, an interactive stage show which opened in 2010 and continues to tour today. Star Trek The Exhibition was also co-produced by the company.
The unit also doubles as a Star Trek archive for the products they have licensed – some of which actually having turned up in live-action productions – as well as for the original production documents and art that have been created for the live-action productions throughout the history of the franchise, serving as a reference source for authors of licensed reference works, though a considerable amount of the latter has been sold off in the 2006-2008 wave of Star Trek auctions.

Established in 1967 as part of Paramount Television, while Star Trek: The Original Series was in production, the unit was known as the "Paramount Publicity Department", headed by Howard McClay and Frank Wright, and it was they, aside from handling the contemporary Star Trek merchandise, who provided author Stephen Edward Poe with the illustrative material for the first Star Trek reference book, The Making of Star Trek. Poe also had professional dealings with the department, as he was the account manager for model kit company AMT in regard to their Star Trek model kit line. (p. 15)
