Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
Pioneer was the first company with a functioning blue laser HD optical disc prototype, thanks to an exclusive partnership with the then world's only blue-violet laser optical pickup manufacturer, Nichia Corp. Sony was hard on Pioneer's heels, and Pioneer and Sony decided to save R&D costs by forming a partnership which proceeded to draw in quite a few other manufacturers along the way. Sony is MUCH larger than Pioneer, and has MUCH deeper pockets, so in spite of being a key developer of the Blu-ray format, Pioneer is more than happy to let Sony take the marketing ball and run with it. That's what royalties are all about! ;-)
