Telegram announced today that it has reached 400 million subscribers and has shared a list of new features it would offer its users in 2020. The list includes secure group video calls, a feature that its three main competitors have had for a while. blog, Telegram founder Pavel Durov said: "Video calls in 2020 are very similar to messaging in 2013. There are apps that are either safe or usable, but not both. Please fix it and we will focus on securing group video calls in 2020." . This obviously came as a blow to Zoom, which faces many security concerns as its user base has grown exponentially in the post-lockdown world. However, there has been no comment on what has delayed the transition to video calls, especially since its main competitors Messenger, WhatsApp and Snapchat had already launched video calling services long ago. The company said that 1,5 million users sign up for Telegram every day, so the journey to 500 million users should be quite short. WhatsApp, which has 400 million users in India alone, has more than two billion users worldwide. And it often happens that Telegram witnesses an increase in the user base when WhatsApp reports any glitch. Durov has worked hard in the past to criticize WhatsApp for its security breaches, saying people shouldn't have been surprised when reports of spyware installed by him surfaced last year. In fact, many users have switched allegiances due to a variety of features like folders and cloud storage. However, these same features caused problems for Telegram as they were used to distribute and download illegal copies of movies, songs, etc. < p lang="en" dir="ltr">Why WhatsApp will never be secure https://t.co/kHfTiWdNQw15 May 2019 As part of its offerings, Telegram today unveiled a gallery of 20,000 stickers and a new menu of attachments for android. In the context of user endorsement, he also announced the creation of a database of educational tests for students with an offer of 400,000 euros to the creators for the development of such tests. However, the question is whether Telegram left all its innovations too late. Or is there still a chance to compete in this crowded market?
