Telegram was started in 2013 by the brothers Nikolai and Pavel Durov, the creators of VK, the largest social network of Russia. Telegram Messenger LLP is an independent nonprofit company located in Berlin, Germany, that is not connected to UK.
In April 2018, Russian court ruled to block Telegram in Russia. Some Russians tried to circumvent the ban by using open proxies in other countries.
Telegram lets its users send voice notes, photos, videos and files of all types. Groups can also have a maximum of 200,000 members. Telegram uses a similar system of message read statuses to WhatsApp, with 1 check=sent, 2 checks=read (opened)
