The Business Model of Skype

Skype is a proprietary telecommunications application that specializes in videotelephony, videoconferencing, and voice calls over the Internet. Additionally, it includes instant messaging, file transfer, and debit-based calls to landline and mobile phones (through regular telephone networks). Skype's initial implementation utilized a mixed peer–to–peer and client–server architecture. Today, Skype is available on a variety of desktop, mobile, and video game console platforms and is operated by Microsoft subsidiary Skype Technologies. Skype was used by 100 million people on a monthly basis and 40 million people on a daily basis as of March 2020.
