Video-chatting gained a lot of steam in 2006, and Microsoft wanted to streamline the process by introducing the LifeCam brand of webcams. All were optimized for Windows Live Messenger, and boasted decent video quality and integrated microphones. They also came with a simple button that would bring up a tool to show who was online, and allow you to connect instantly.
The first two models were the VX-6000, which took 5.0 megapixel stills and 1.3 megapixel video, and the VX-3000 (pictured), which took 1.3 megapixel stills and 640-by-480 pixel video. Today there are still a ton of LifeCam products ranging in quality and price to fit any webcam need.
