WhatsApp is a smartphone messaging program that functions similarly to BlackBerry Messenger.
WhatsApp Messenger is a cross-platform messaging tool that allows us to send and receive messages without having to pay SMS rates because it uses the same internet data plan as email, online surfing, and other applications.
For data communication, the WhatsApp Messenger app utilizes a 3G or WiFi connection. We may use WhatsApp to have online discussions, transfer files, and swap images, among other things.
History
WhatsApp was originally designed for iPhone users, but as the app has evolved, it is now accessible for BlackBerry, Android, Windows Phone, and Symbian devices. After Swype and NHL Gamecenter Premium, WhatsApp was the third best-selling application downloaded through the Nokia Ovi Store until November 2010.
Brian Acton
In 2009, two men named Brian Acton and Jan Koum started WhatsApp Inc. Both are former Yahoo employees who worked in senior positions.
Both have spent almost 20 years at Yahoo. Jan Koum was the one who came up with the notion of making an app that could publish someone's status when they couldn't be reached for any reason.
Acton was also invited to collaborate with Koum. As a result, they founded WhatsApp Inc, a technology startup based in Santa Clara, California.
However, just a few people were interested in the broadcast status application. WhatsApp took off in the second half of 2009 after they launched a messaging feature.
Jan Koum had a difficult childhood in a village on the fringes of Ukraine, yet at the age of 37, he became a billionaire.
Koum's success, on the other hand, is inversely related to what he went through as a child. Jan Koum went to a school that didn't have a restroom on the premises. Students had to brave the cold just to go to the bathroom, with temperatures in Ukraine reaching -20 degrees Celsius.
Koum, like other communist countries, finds it difficult to communicate. The reason was that the Soviet Union had implemented a communist system at the time.
Koum is so poor that he does not own a computer. The door to social life has been shut completely. Jan Koum didn't have his first computer until he was 19 years old.
WhatsApp Inc. is said to have a staff of around 20 individuals. The majority of them work as technologists. According to the most recent figures from August 2012, WhatsApp users globally transmit 10 billion messages every day. In April 2012, however, a 'new' 2 billion messages were sent.
Jan Koum
WhatsApp is available for all existing mobile operating systems. From iOS, Android, BlackBerry OS, BlackBerry 10, Nokia Symbian, Nokia Series 40 and also Windows Phone.
WhatsApp is actually not completely free. The WhatsApp application on the iPhone can be used for free for a year, then you are required to pay. Likewise on other platforms.
WhatsApp said it was deliberately charging fees in exchange for a product that was reliable and without ads. Since the beginning, this application has been designed for a fee so that the WhatsApp team can focus on developing products.
WhatsApp, which was founded in 2009, was later purchased by Facebook in February 2014 for a value of USD 19 billion or around IDR 282 trillion (USD = IDR 12,108). Jan Koum is on Facebook's board of directors.
