I created the Selenium project 6 years ago. These days, I'm working on my own Selenium-based startup, Sauce Labs ( http://saucelabs.com ) -- We offer commercial support for Selenium and have a cloud-based web app testing service, too, called Sauce OnDemand.
Regarding Google, you might be thinking of the on-going merger between the Selenium and the WebDriver projects. WebDriver was created by Googler Simon Stewart. He currently works at Google, but WebDriver was created when Simon was still at ThoughtWorks. Also, I am a former Googler (and former ThoughtWorker), and worked on Selenium during my time at both places.
