List of multiple-system operators
A multiple-system operator is an operator of multiple cable or direct-broadcast satellite television systems. A cable system in the United States, by Federal Communications Commission definition, is a facility serving a single community or a distinct governmental entity, each of which has its own franchise agreement with the cable company. Though in the strictest sense any cable company that serves multiple communities is an MSO, the term today is usually reserved for companies that own multiple cable systems, such as Rogers Communications, Shaw Communications, and Videotron in Canada; Altice USA, Charter Communications, Comcast and Cox Communications in the United States; or Virgin Media in the UK.
