The type attribute contains the MIME type of the file specified by the , and browsers can use the type to immediately skip videos they don't understand. In the early days, native web technologies such as HTML didn't have the ability to embed video and audio on the Web, so proprietary (or plugin-based) technologies like Flash — and later, Silverlight (both of which are now obsolete) — became popular for handling such content. Like the .WEBP image file, .WEBM was created by Google as an efficient means of disseminating media to a large audience. The
