WhatsApp was founded in February 2009 by Brian Acton and Jan Koum, both former Yahoo employees. The name is a play on the phrase “What’s up?”. The company was incorporated in California in the same year.
The app quickly grew into one of the most popular messaging platforms worldwide. By early 2020, it had over 2 billion users. In February 2014, Facebook (now Meta Platforms) acquired WhatsApp for approximately 19 billion US dollars, making it one of the largest technology acquisitions in history.
WhatsApp is now a subsidiary of Meta Platforms. Under Meta’s ownership, its user base grew to nearly 3 billion users. Mark Zuckerberg has stated that WhatsApp contributes about 10 billion US dollars in annual revenue to Meta.
WhatsApp provides secure messaging and calling services in more than 180 countries. Notable developments include:
WhatsApp Business (2018) for small businesses
WhatsApp Cloud API / Business Platform (2022) for enterprises
End-to-end encryption since 2016, with encrypted backups added in 2021
Multi-device support, video calls, large group chats, and channels
Recent features such as message editing, voice transcription, and AI integration
WhatsApp is the primary messaging app in many regions, including the Americas, Europe, South Asia, and Africa. By 2023, the app had around 2.7 billion monthly active users, with 200 million business users. In the U.S. alone, about 100 million people use WhatsApp.
WhatsApp has faced criticism regarding privacy, especially after its acquisition by Facebook. In 2017, the European Commission fined Facebook for misleading statements about data sharing. Co-founder Jan Koum later resigned due to concerns over user privacy, while Brian Acton co-founded the Signal Foundation. Despite controversies, WhatsApp remains known for its strong encryption and steps to fight misinformation, including limits on message forwarding.
