As of October 2025, three billion users were accessing the WhatsApp messenger on a monthly basis. The app’s reach in usage penetration is particularly strong in markets outside the United States, and it is one of the most popular mobile social apps worldwide. WeChat amassed 1.41 billion users, and Facebook Messenger was reported to have a potential ad reach of 942 million users worldwide.
Instant messaging is a type of online chat that offers real-time text transmission via the internet. Since the appearance of the smartphone and the subsequent explosion of mobile apps, low-cost or free chat and social messaging apps have proven themselves as a cheap alternative to operator-based text messaging via SMS. Many messenger apps offer features such as group chats, the exchange of graphics, video, and even audio messages, as well as stickers or emoticons.
