All I can say is well done Google, they’ve truly done the right thing and could have single-handedly helped to preserve the future of video on the web! They’ve also hit the ground running with a very impressive list of people backing the format, such as:
nVidia
Intel
ARM
Qualcom
Adobe Flash platform
Opera
Mozilla / Firefox
CORE Codec
AMD
Logitech and more!
Why is this all so important?
