The latest research released today by media analysts Screen Digest (www.screendigest.com), examines the evolution of the high-definition video market. The research includes detailed forecasts to 2011 for consumer sales and revenues of both new video formats for W Europe and the US. Screen Digest believes that whilst Blu-ray Disc (BD) is selling more units than rival HD DVD at the moment, in the longer term both formats will establish a viable installed base, allowing them to co-exist for the foreseeable future. As a result, Screen Digest has calculated that those Hollywood studios that opt to support a single format only could be missing out on significant revenues, potentially eschewing over $270m of consumer spending in 2008 alone. Blu-ray-exclusive studios Sony, Fox and Disney could miss out on $175m in consumer spending by not publishing their films on HD DVD.
