We launched Telegram 6 years ago, on August 14, 2013 – and immediately set to work on the next update. That‘s how it’s been ever since.
After a little while we noticed that our work not only brings progress to Telegram – but also results in the evolution of messaging as a whole. It is heartwarming to see our solutions and design decisions adopted as de facto standards across the board.
To keep you entertained while we‘re working on this month’s second update, we've compiled a brief history of Telegram. It ended up rather on the ‘humongous’ side of ‘brief’ – but it's not like the next update is tomorrow either. So read on.
Oh, and if you want to give us a gift, bring two of your best friends to Telegram today.
A (Not So) Brief History of Telegram
For some reason, we started writing this backwards – from the latest update to the primordial summer of 2013. And then it was too late to change the order because the guy who compiled the post said he would go on a hunger strike if we tried.
So if you're a fan of chronology, please jump to the end and scroll up from there. (By the way, we decided we're going to keep this post up to date as new updates arrive.)
September 2019
Scheduled Messages, Reminders, Custom Cloud Themes and More Privacy
The end of summer brought scheduled messages and reminders to better keep track of important tasks and appointments. On the visual side, shareable Custom Cloud Themes came to all platforms, along with more animated emoji.
An important privacy option was added for those who need it most – Who Can Find Me By My Phone Number. This new setting can prevent random users (or government organizations) from being able to match a number from their device's contacts to your Telegram account.
On Telegram since September 2019:
- Scheduled Messages and Reminders
- Custom Cloud Themes

Following the success of animated stickers, this update also introduced animated emoji for

Animated Stickers Done Right
The July update introduced animated stickers. We managed to achieve a smooth 60 FPS at just 20-30 KB per sticker. Animated stickers consume less bandwith than static ones and less battery than GIFs, while commanding more attention than the two combined.
Here are some sample animated sets in case you missed them: Hot Cherry, Tidy Tie Tom, Resistance Dog, Fred the Pug, Melie the Cavy, Earl the Wolf, Egg Yolk
These stickers are powered with uranium and dreams and are guaranteed to keep going forever.

On Telegram, your phone number was never visible to random people in groups, the default being ‘My Contacts’. This update offered even more control via Settings > Privacy & Security > Phone Number.
The update also introduced an easier way to integrate web services with Telegram, adding one-tap authorization via bots. Last but not least, it offered two new ways of adding comments to channels – via Comments.app and connected discussion groups. (We didn't start the flame war.)

Android design got a major overhaul. Aside from the visual improvements, this update added a three-lines-per-chat view option for the Android chat list (similar to the iOS default), as well as bulk actions in the chats list to easily delete, archive or mute multiple chats at once.

This update also introduced presets for autodownload settings to switch between Low, Medium, High and Custom data consumption in a few taps. Default settings for data usage have become more generous but depend on the affordability of mobile data in each particular country.

There were two Telegram updates on November 19, 2014.
Hiding Last Seen Time – Done Right
This update expanded Privacy Settings to cover Last Seen status, allowing unprecedented flexibility with ‘Always Share With’ and ‘Never Share With’ exceptions for individual users.
This was also when account self-destruction was introduced. Telegram doesn‘t aim to accumulate and store your data when you don’t need it anymore. So if you throw away your SIM card and it gets a new owner in 6 months, they won't access your chats.
Material Design on Android, Instant Search for Messages and more
November '14 also delivered Instant Full-Text Search to iOS and Android. Since then you can quickly find any message you ever sent or received on Telegram.
GIF search was first supported on iOS. The Android app got a massive redesign, consistent with material guidelines.

Public usernames, smaller timers for Secret Chats, and more
October '14 marks the beginning of properly recorded history on Telegram. The first update ever to be described in a blog post brought public usernames, adding the ability to share your Telegram contact without disclosing your phone number.
Secret Chats got a major upgrade, with self-destructing media showing blurred thumbnails and starting the countdown only after they are first opened. This prevented them from disappearing before actually being viewed. This was also when screenshot notifications were first introduced.
Telegram for Android received several updates, adding support for Android Wear and tablets, as well as video compression.

Congratulations on completing this (not very) brief course on the history of Telegram. You just got an honorary PhD in Instant Messaging – unless you simply jumped down here, in which case you still have a long way 
to go to get back to the top.
Armed with this much knowledge, you should probably join our Volunteer Support Force. And if that‘s not your cup of tea – just tell us in the comments which feature you didn’t know existed.
