Zoom has admitted it doesn’t have 300 million daily active users. The admission came after The Verge noticed the company had quietly edited a blog post making the claim earlier this month. Zoom originally stated it had “more than 300 million daily users” and that “more than 300 million people around the world are using Zoom during this challenging time.” Zoom later deleted these references from the original blog post, and now claims “300 million daily Zoom meeting participants.”

The difference between a daily active user (DAU) and “meeting participant” is significant. Daily meeting participants can be counted multiple times: if you have five Zoom meetings in a day then you’re counted five times. A DAU is counted once per day, and is commonly used by companies to measure service usage. Only counting meeting participants is an easy, somewhat misleading, way to make your platform usage seem larger than it is.

The misleading blog was edited on April 24th, a day after the numbers made headlines worldwide. After The Verge reached out for comment from Zoom, the company added a note to the blog post admitting the error yesterday, and provided the following statement:

“We are humbled and proud to help over 300 million daily meeting participants stay connected during this pandemic. In a blog post on April 22, we unintentionally referred to these participants as “users” and “people.” When we realized this error, we adjusted the wording to “participants.” This was a genuine oversight on our part.”

Zoom’s growth has been impressive, but the company has not actually provided a daily active user count. Zoom usage has soared from 10 million daily meeting participants back in December to 300 million this month. Rivals like Microsoft Teams and Google Meet appear to be closing the gap, though. Microsoft said yesterday it now has 75 million daily active users of Teams, a jump from 70 percent in a month. Microsoft also recorded 200 million meeting participants in a single day this month.

Google Meet is adding roughly 3 million new users each day, and hit over 100 million daily Meet meeting participants recently. Cisco also revealed earlier this month that it has a total of 300 million Webex users, and saw sign-ups close to 240,000 in a 24-hour period. Cisco has not yet provided daily meeting participant numbers, or daily active user counts.

Google, Microsoft, Facebook, and others are still chasing Zoom with new features and free services. Google made its Meet service free this week, and both Microsoft and Google have increased how many people you can see simultaneously in response to Zoom’s popular gallery view.
