Please help me remember the site with office video streaming in the background

Question

HTML

Good evening. Please help me remember the address of the website of a foreign web studio, where in the background there was a video streaming office. In principle, it is not necessarily a web studio, any company can.
I will not refuse a brief description of the best way to implement such an idea.

Connect any webcam, install software from the site and broadcast your video.
The site also has a gallery of cameras - maybe you will find what you need
