Pay TV showdown
Ofcom has asked the Competition Commission to investigate the sale and distribution of premium subscription pay TV films.
The regulator said it is concerned about the way the films are sold and distributed as it "creates a situation in which Sky has the incentive and ability to distort competition."
It warned: "The end result for consumers is less choice, less innovation and higher prices."
First-run Hollywood films are particularly important to competition in the pay TV sector as a large number of consumers hanker after the latest releases via subscriptions, as close to the box office release as possible. The regulator believes the film content is a key factor for many consumers when signing up to a pay TV service.
Ofcom referred its concerns to the Competition Commission as it cannot address them fully using its own powers. The Commission has a maximum of two years to investigate.
It has specifically referred two movie markets: the rights to films sold by the major Hollywood studios to broadcast films for the first time on pay TV and the wholesale supply of pay TV packages containing film channels, which are based on those rights.
Ofcom said its analysis has identified features within the two markets, which in combination could reduce combination.
The regulator began investigating the pay TV market in 2007 after BT, Setanta, Top UP TV and Virgin Media raised concerns about Sky's domination of major sporting events. This resulted in the ability of multiple pay TV providers to offer Sky Sports 1 and Sky Sports 2.
