WhatsApp Messenger

WhatsApp is a globally recognized instant messaging and voice-over-IP service. It allows users to send text messages and voice messages, make voice and video calls, and share images, documents, user locations, and other content. Originally launched as a small startup in California, it has grown into one of the most essential communication tools in the world, utilized by billions of users across various mobile and desktop platforms.

The service was founded in 2009 by Jan Koum and Brian Acton, former employees of Yahoo!. After a period of rapid independent growth, the company was acquired in one of the tech industry’s largest transactions. Today, it operates as a core part of a major social technology conglomerate, maintaining a focus on end-to-end encryption and cross-platform accessibility while expanding into business communication tools.
