Best Brains, Inc. (first known as Hair Brain Productions) is an entertainment company based in Eden Prairie, Minnesota. It is the production company originally responsible for Mystery Science Theater 3000. MST3K ceased production in 1999 and the Best Brains studio was closed. Since then, the company's only functions were to sell MST3K-oriented merchandise and negotiate distribution, currently through Shout! Factory. In 2015, it was announced that Shout! Factory had purchased all rights to Mystery Science Theater 3000 from Best Brains, Inc. for an undisclosed sum.
