Google and Panasonic (Matsushita Electric Industrial) are partnering in the development of televisions that display Internet content like video and photos.

Users will be able to browse videos from YouTube and photos from Picasa Web Albums directly through the new TVs starting next spring.

“We are thrilled to introduce Panasonic VIERA PZ850 series Internet-Connected HDTV’s with virtual one-click access to YouTube and Picasa Web Albums from Google,” said Toshihiro Sakamoto, President of Panasonic AVC Networks Company. “This is the first time mainstream consumers will be able to easily enjoy YouTube videos from the living room with the enhanced quality of a fully integrated widescreen TV experience. YouTube is already a huge worldwide sensation, and Panasonic VIERA Internet-connected HDTV’s will greatly expand users’ entertainment options.” [Panasonic Pressroom]

In addition, Matsushita has unveiled a 150-inch plasma television, which it says is the world’s biggest, during the Consumer Electronics Show in Las Vegas by Toshihiro Sakamoto, president of Panasonic AVC Networks Co.

The new HDTV screen measures 12.5 feet diagonally and offers four times better resolution than full high-definition 1080p picture quality. It will be launching in 2009 at an undisclosed price.
