Skype: A Comprehensive Overview

Skype is a renowned telecommunications application that facilitates Internet-based communication. Developed by Skype Technologies, a division of Microsoft, Skype is famed for its innovative IP-based videotelephony, videoconferencing, and voice calling capabilities.

Origin and Development

Skype was initially created by Niklas Zennström, Janus Friis, and four Estonian developers. It made its debut in August 2003 and quickly gained popularity for its ability to bridge geographical distances through the Internet. In September 2005, eBay acquired Skype for $2.6 billion, marking a significant milestone in its commercial journey. Later, in September 2009, Silver Lake Partners, Andreessen Horowitz, and the Canada Pension Plan Investment Board purchased a substantial 65% stake from eBay, setting its valuation at $2.92 billion.

Features and Functionality

Skype provides an array of features that extend beyond basic communication. These include:

Instant Messaging: Users can engage in real-time conversation through text messages.
File Transfer: Facilitates the sharing of files across different devices.
Voice Calls: Allows users to make calls to other Skype users and debit-based calls to landlines and mobile phones.
Videoconferencing: Supports face-to-face communication through video links.
Skype Translator: An innovative speech-to-speech translation tool that breaks language barriers in real-time.

Skype Technologies

Skype's backend is powered by proprietary technologies and protocols that ensure seamless communication. The Skype protocol, although now discontinued, was a significant component of its operation. The robust security measures employed by Skype have also been a focal point of its development, ensuring safe and reliable communication for users globally.

Integration and Evolution

With the acquisition by Microsoft, Skype's integration with Microsoft services expanded its functionality and reach. Skype for Business, formerly known as Microsoft Lync and Office Communicator, was a significant offering for enterprise communication until its eventual replacement by Microsoft Teams. This transition underscores Microsoft's strategy to consolidate its communication tools under a unified platform.

Discontinued Services

Over the years, Skype introduced and phased out several services. Notable among them was Skype Qik, a video messaging service, and Skype for Business Server, which provided real-time communications infrastructure for businesses.
