MPEG LA announced that its AVC Patent Portfolio License will continue "not to charge royalties for Internet Video" that is free to end users ("Internet Broadcast AVC Video") during the entire life of this License". Meaning that Opera and Mozilla Firefox will now be able to adopt the video codec standard without worrying of paying royalties, joining browsers Internet Explorer 9, Safari 5 and Chrome in using the codec standard. This change could make H.264 the video format standard for HTML5. Both Opera and Mozilla announced they would be supporting the open-source Ogg Theora video codec.
Both Microsoft and Apple own patents in H.264 standard, while Google owns and develops VP8/WebM, another royalty-free video codec standard.
