RateMyProfessors.com (RMP) is a review site, founded in May 1999 by John Swapceinski, a software engineer from Menlo Park, California, which allows college and university students to assign ratings to professors and campuses of American, Canadian, and United Kingdom institutions. The site was originally launched as TeacherRatings.com and converted to RateMyProfessors in 2001. RMP was acquired in 2005 by Patrick Nagle and William DeSantis. Nagle and DeSantis later resold RMP in 2007 to Viacom's MTVU, MTV’s College channel. Viacom owned and operated RateMyProfessors.com for a decade. Cheddar announced its acquisition of RMP from Viacom in 2018. RMP is the largest online destination for professor ratings. The site includes 8,000+ schools, 1.7 million professors, and over 19 million ratings.
