Every day, thousands of scheduled events happen on the Internet. These range from live video and audio shows to chats, poker tournaments and sales on Woot and Groupon. The problem, though, is that there is no single place to find out about these upcoming events. Live Matrix, which just launched, wants to change this. The service aims to be a TV Guide for all scheduled events on the Internet and currently indexes about 100,000 events per week.

What is Magma? Well, it's best known as molten underground rock waiting to explode out of a volcano and flow viscously through your run-of-the-mill Polynesian village. But as of today, Magma is also a video site created by Rocketboom founder Andrew Baron. Baron launched the site in the hopes that it fills a need for audience-focused content. Just as TV Guide and the Billboard charts offer entry points into their industries, Magma offers an entry point into web video. The company hopes to become the new search interface for video exploration.
