An April 2020 survey of 1,110 US companies by Creative Strategies showed that 27 per cent of businesses primarily used Zoom for video calls and meetings, compared to 18 per cent that used Teams, and 15 per cent that used Skype.
(Eric Yuan, Zoom’s founder, has been working on web conferencing software since he arrived in the US in 1997 from China to work for WebEx). Not that people are using either as much as Zoom, which benefited both from being free to download and more reliable than its competitors.
By July 2021, Skype will disappear, and anyone wanting to make a business video call through Microsoft products will instead have to use Teams.
