Microsoft Edge will shortly support Google's open-source WebM video format

Microsoft has mentioned that it is working to add support for Google’s WebM video file format — an open-source royalty-free alternative to the H.264 format — in its Edge browser. With Google ditching Flash Player for HTML5 earlier this year, native support for the WebM format will ensure better compatibility with video streaming sites such as YouTube.
