BTV Sports is the brand name for a group of sports-oriented TV channels owned & operated by WMFL Corporation under WMFL Worldwide. BTV Sports is the dominant subscription TV sports brand in the United Kingdom & Ireland. It has played a major role in the increased commercialization of British sport since 1990, sometimes playing a large role in inducing organisational changes in the sports it broadcasts, most notably when it encouraged the Premier League to break away from the Football League in 1992.
