"By 2011 online video in the U.S. will represent eight percent of total home entertainment revenues, with Western Europe close behind at seven percent," said Mai Hoang, analyst at Understanding & Solutions.

"What's more, multiple formats will coexist in the future, and no one format will control the home entertainment landscape, quite unlike the domination of DVD since the demise of VHS," Hoang added.

"The new generation of high definition video formats will also help to shore up packaged media's presence within home entertainment revenue streams," eMarketer reported.
