Here's an interesting bit of news. At a recent shareholders' meeting, Toshiba President Atsutoshi Nishida announced that the company is still interested in developing a unified DVD format.
Toshiba Corp. (6502.T) said on Tuesday it would still like to develop a unified format for advanced optical DVD discs, but two competing -- and incompatible -- products are likely to hit the market at first.

Toshiba is a leading proponent of next-generation HD DVD optical disc technology, which competes with the Blu-ray standard promoted by Sony Corp (NYSE:SNE - news). (6758.T) and Matsushita Electric Industrial Co. (6752.T), a maker of Panasonic brand electronics.

"We have not given up on a unified format. We would like to seek ways for unifying the standards if opportunities arise," Toshiba President Atsutoshi Nishida told an annual shareholders' meeting.
