WhatsApp: Your Daily Messenger to Connect with Friends and Family

I. Introduction

WhatsApp was founded in 2009 by two former Yahoo employees, Brian Acton and Jan Koum. The app was initially created as a simple messaging service for people to stay in touch with their friends and family. However, it quickly grew in popularity and by 2014, it had over 400 million monthly active users. In 2015, Facebook acquired WhatsApp for $19 billion, making it one of the largest tech acquisitions in history.

WhatsApp is a messaging app that allows users to send text messages, voice messages, make voice and video calls, and share media such as photos, videos, and documents. It also has a feature called Status, which allows users to share updates with their contacts for 24 hours before they disappear. WhatsApp’s end-to-end encryption ensures that all conversations and media shared on the app are secure and private. Additionally, WhatsApp has a business version called WhatsApp Business, which provides features specifically designed for businesses to communicate with their customers.
