What is Telegram?

Pavel Durov is the founder, owner, and CEO of Telegram. He left Russia in 2014, after losing control of his previous company for refusing to hand over the data of Ukrainian protesters to security agencies. Telegram is a secure messaging and audio calling cloud-based app that allows you to send messages, photos, videos, and files of any type to your contacts for free. Telegram is an instant messaging app; people use it to communicate with others. Telegram is popular because it doesn't require a phone number for use. Some people seek out Telegram for its custom security settings, including Secret Chats. However, it's important to note this feature is not enabled by default. New York University professor Samuel Morse (pictured at left) began working on his version of the telegraph in 1832; he developed Morse Code (a set of sounds that corresponded to particular letters of the alphabet).
