Skype

Founded in 2003, Skype revolutionized how people communicate by enabling free and affordable internet-based voice and video calls, transforming both personal and business interactions globally. Acquired by Microsoft in 2011 for $8.5 billion, Skype’s technology and massive user base became a cornerstone of Microsoft’s real-time communication strategy. Over time, Skype integrated with numerous Microsoft products, expanding its reach across devices like Xbox, Windows, and Outlook.
