For those who are self-quarantining or otherwise isolated due to the coronavirus pandemic, the Internet has transformed from a simple source of entertainment to a vital lifeline almost overnight. Zoom has become one of the most fundamental tools for group gatherings and not only are businesses using it, but families, schools, and groups of friends as well.

According to The New York Times, more than 600,000 people downloaded Zoom in a single day last month. Zoom memes are everywhere now, and social media is full of people screencapping their Zoom conferences with accompanying hashtags like #unity, #isolation, and #coronavirussucks.

All of this buzz made Zoom shares soar this year, valuing the company at $29 billion — more than airlines like Delta, American Airlines or United Airlines.

Zoom has been preparing for this moment since the novel coronavirus outbreak in China. Even then it was evident that its primary customer base — videoconferencing desk workers — would become more reliant on its services while living in quarantine. So the company began closely analyzing its capacity and started hosting free training sessions. In China, Zoom even got rid of its 40-minute limit for free calls.
