What is Telegram?

Telegram is a cloud-based instant messaging and voice over IP (VoIP) service founded by Russian entrepreneur Pavel Durov. It was launched in 2013 and has since gained popularity for its focus on security, privacy, and features such as end-to-end encryption, self-destructing messages, and large group chats.
