Following Toshiba Corp.'s cancellation of HD DVD support, other companies involved in promotion of the format have decided to cease their efforts as well. On the 28th of March the HD DVD promotion group said that it dissolves.

"The HD DVD Promotion Group was dissolved as of March 28, 2008,  and the website was closed accordingly. Please access to DVD Forum for HD DVD formats, and DVD Format/Logo Licensing Corporation for format books and its license. Regarding the HD DVD products, please contact each selling agency directly," a short statement located on the web-site of the group reads.

With no support from any company among the 70 backers of the HD DVD, which were in promotional group, the are almost no chances that the format will continue to be on the market in any form. Still, it is possible that companies like LG Electronics will continue to support existing movie collection with players capable of both Blu-ray disc and HD DVD playback.

Back in mid-February Toshiba announced that it would stop making HD DVD equipment and will not support the format any longer. Following the announcements, studios who exclusively backed HD DVD - Paramount/Dreamworks and Universal Pictures - announced plans to release movies on Blu-ray disc format. As a result the future of HD DVD was doomed.
