Zoom – Video Conferencing and Online Meeting Platform

What is Zoom?

Zoom is a leading video conferencing and online communication platform that has transformed how people connect for work, education, and personal interactions. Founded by Eric Yuan in 2011, Zoom Video Communications has grown to become synonymous with video meetings, serving millions of daily meeting participants across businesses, schools, healthcare providers, and individuals worldwide.

The platform provides high-definition video and audio conferencing, screen sharing, virtual backgrounds, breakout rooms, and extensive collaboration features. Zoom’s reliability, ease of use, and cross-platform availability have made it the go-to choice for remote work, online education, telehealth, and virtual events of any scale.

From one-on-one conversations to webinars with thousands of attendees, Zoom scales seamlessly while maintaining quality. Its integration with calendar applications, productivity tools, and third-party services creates a comprehensive communication ecosystem that supports modern distributed work patterns.
