It’s twenty years since Sky started to change the face of broadcasting in Britain, beginning with just four channels in a direct to home satellite package that included the first 24-hour news channel in Europe. Since then, Sky has repeatedly taken risks to advance its television technology and broadband services, leading innovation in interactive television, driving the adoption of digital, personal video recorders and high-definition. Sky has been subject to stringent and rigorous regulation as it has become increasingly successful and powerful, largely through excellently executed commercial strategy. In its latest response, Sky has hit back at what it terms “highly interventionist regulation”. Meanwhile, in a ruling that appears to have caught the terrestrial public service broadcasters on the hop, the Competition Commission has killed their Kangaroo plans for a joint video-on-demand venture that was seen by their competitors as a cosy cartel. It should come as no surprise that they were judged according to the same standards that would be applied to any other commercial venture. The challenge for regulators is to maintain a careful balance to preserve open competition and choice that ultimately benefits consumers.
