PFF was founded by Neil Hornsby in the United Kingdom. Dissatisfied with some limitations of standard statistics, Hornsby began grading players in 2004. The staff gradually expanded over next few years, and the site was launched in 2007. The 2007 NFL season is the first season for which PFF has complete data. For the 2011 season, PFF provided customized data to three NFL teams, agents, media and NFL players.   In 2014, sports commentator and former NFL player Cris Collinsworth bought a majority interest in the service, which moved its operations to Cincinnati , where Collinsworth resides.   PFF began collecting data for every NCAA Division-I college football game in 2014.
