WhatsApp is a popular instant messaging and voice-over-IP (VoIP) app owned by Facebook, Inc. The app was founded in 2009 by two former Yahoo employees, Brian Acton and Jan Koum, and was later acquired by Facebook in 2014.
WhatsApp allows users to send text messages, voice messages, and make voice and video calls over the internet, rather than through traditional cellular networks. The app is available for free on a variety of mobile and desktop platforms, and is used by billions of people around the world.
One of the key features of WhatsApp is its end-to-end encryption, which ensures that messages and calls are kept private and secure. The app also allows users to create group chats, share photos and videos, and make voice and video calls with multiple people at once.
WhatsApp has been particularly popular in emerging markets, where it has helped to provide affordable and reliable communication services to people who might not have access to traditional phone or internet services. The company has also launched a range of business features, such as WhatsApp Business, which allows companies to communicate with customers and manage their messages more effectively.
Today, WhatsApp continues to be a popular communication app, providing users with a secure and reliable way to stay connected with friends, family, and colleagues around the world.
