WebRTC is a new standard that enables real-time voice, video, and file sharing directly in web applications without the need for plug-ins, revolutionizing communication. It faces both support from major companies like Cisco and Mozilla and resistance from Microsoft, who prefers proprietary solutions. The integration of WebRTC into websites will transform customer service and enterprise applications, shifting the role of websites to become interactive communication hubs.
