Number of monthly active WhatsApp users 2013-2020
WhatsApp WhatsApp is a cross-platform instant messaging service for smartphones that relies on the internet for the transmission of messages. Based on a low-cost subscription model, WhatsApp is a cheap alternative to carrier-billed text messaging via SMS, especially for international or group messaging. The mobile messaging app enables users to share text, image and video messages. In the United States, the WhatsApp audience amounted to 68.1 million users in 2019 and is set to grow to 85.8 million users in 2023.
WhatsApp is especially popular in markets outside the United States while facing strong competition from Asia-based social messenger apps such as WeChat, LINE or Kakaotalk. WhatsApp’s popularity in emerging mobile markets is not only based on their low-cost business model but on many of its features.
