Telegram is a freeware, cross-platform, cloud-based instant messaging software and application service. The service also provides end-to-end encrypted video calling, VoIP, file sharing and several other features. It was initially launched for iOS on 14 August 2013 and Android in October 2013.
Telegram is supported by Pavel Durov and his brother Nikolai. Pavel supports Telegram financially and ideologically while Nikolai’s input is technological. To make Telegram possible, Nikolai developed a unique custom data protocol, which is open, secure and optimized for work with multiple data-centers. As a result, Telegram combines security, reliability and speed on any network.
