WebRTC has progressed significantly in its first 3 years, moving from early experiments and proof of concepts to widespread adoption in browsers and innovative business applications. It started as an open source project at Google in 2011 and is now both an open standard specification and software stack. Major browsers like Chrome, Firefox, and Opera now support WebRTC natively. While adoption started with video chat apps, the technology is now used in verticals like education, healthcare, and more. Over 600 projects from vendors use WebRTC. In the next few years, the technology will continue transitioning to broader use in cloud services and reinventing communications with support from more players like Microsoft.
