Answer
Telegram was founded in 2013 by Nikolai Durov and Pavel Durov, brothers who had previously founded VKontakte, a Russian social network. Telegram is a messaging app that focuses on security and speed. It uses end-to-end encryption, which means that messages can only be read by the sender and recipient, and not by anyone else, including Telegram. Telegram is also very fast, and can send messages, photos, and videos quickly.
