Raging in the backrooms of Hollywood this summer has been a battle that will play out in the aisles of Wal-Mart and Target.
Until recently, it had appeared that the two camps vying to set the standard for next-generation DVDs would settle the score this holiday season.
But last-ditch maneuvering in recent weeks has all but assured that the format war will extend well beyond December, keeping many home-movie buffs from laying their money down until a winner is declared.
It's no wonder that neither rival -- Asian consumer electronics giants Sony Corp. or Toshiba Corp. -- can bear to give in. Licensing fees on equipment that could be worth $10 billion or more over time are up for grabs.
At the moment, Sony's Blu-ray discs have the edge, with a 2-to-1 advantage since January, thanks to support from Walt Disney Co. and News Corp.'s 20th Century Fox, as well as the sale of 1.6 million Sony PlayStation 3 game consoles that play films in the new high-definition format.
But in an attempt to swing momentum in its favor, Toshiba has struck a flurry of deals aimed at winning studio allegiances and securing prized retail space for its HD DVDs.
Toshiba recently paid a collective $150 million to Paramount Pictures and DreamWorks Animation in a bid to buy their support, according to people with knowledge of the terms of the transactions.
Toshiba spokesman Keisuke Ohmori declined to comment on possible marketing payments, but said the two studios had picked HD DVD on the merits, as "the optimum platform" for consumers and film distributors.
Toshiba's expanded partnership, which had already included Universal Pictures, means that many of this summer's biggest movies, including "Transformers" and "Shrek the Third," will be released in video this fall in HD DVD.
The brinkmanship is intensifying. Another major studio, Warner Bros., is being courted by both camps and believed to be mulling over a lucrative offer that could bring such popular titles as "Harry Potter and the Order of the Phoenix" into the HD DVD camp, according to Hollywood insiders who requested anonymity because the talks were confidential.
"Any movement by one of the studios tilts the playing field in one direction or the other," said David Sanderson, head of the global media practice at consulting firm Bain & Co. "It's a bit of jump ball right now."
