Channel 4's digital diversification strategy is a topic we first considered in 2002. At that time, we urged Channel 4 to husband its resources to meet its public service remit and maintain audiences on its terrestrial service, rather than diversify into new digital satellite channels. If anything, the progress of time has reinforced our conclusion that Channel 4's digital diversification strategy is risky. The risks for Channel 4 are greater than for the BBC, since Channel 4's public service remit is funded by advertising alone

On 27th July the BBC will open access to the iPlayer to UK internet users, en route to a hard launch later this summer. This PC-based application allows the user to download BBC TV content after broadcast to view on the PC for a limited time, and provides a TV-like display on the PC. Delays to the launch will mean the iPlayer enters a field already crowded by other broadcasters, including Channel 4's 4oD service, ITV's broadband portal, Sky Anytime, as well as content aggregators such as Joost and Babelgum (both currently in beta)

Ofcom has awarded the UK’s second national commercial digital radio multiplex to Channel 4 Television, having rejected a competing bid from National Grid Wireless

One response to the growth of the satellite and cable households has been for terrestrial broadcasters to launch their own digital channels. These channels are beginning to absorb significant fractions of the total programming budget and in this report we look at the implications for the parent broadcasters. We examine E4, Channel 4’s main satellite entertainment channel, showing that it is likely to remain a drain on the parent for many years to come. Rather than ‘strengthening the brand’ of terrestrial broadcasters, which is the reason normally given for diversification into satellite channels, our research shows that E4 and other services do nothing for the parent company and divert programming expenditure that would otherwise be usefully spent on the terrestrial service.
