It may not be true, that Blockbuster engages in internal censorship. Then again, it may be. Scanning their library of VHS movies, you will run into several movies that have the words "rated version" after the title ("Angel Heart - Rated Version"). Regardless of who did the actual censorship, these are the censored movies.

In addition, it should be noted that there are two categories of Blockbuster stores: corporate, and privately owned franchises. The private franchises retain the Blockbuster name and color scheme, but have fewer rules to obey. There is a Blockbuster somewhere in Rhode Island, for example, that carries uncensored, soft-core porn.
