Almost three years after Google released its WebM video encoding technology as a "free" and open alternative to the existing H.264 backed by Apple and others, it has admitted its position was wrong and that it would pay to license the patents WebM infringes.
[...]
Mozilla and Opera initially also tried to prevent the use of H.264, but have since capitulated to support H.264 as a standard, leaving Google's WebM in virtually the same position it had as a new 1.0 product three years ago, but without any excitement surrounding it. This essentially makes WebM the equivalent of Flash in 2010: resolved of legal challenges but saddled with technical and performance issues, and incompatible with any devices running iOS.
