They then thought of open-sourcing the test tool. ThoughtWorkers in various offices around the world picked up Selenium for commercial projects.
Selenium RC was the first version of Selenium. In 2007, Huggins joined Google. Together with others like Jennifer Bevan, he continued with the development and stabilization of Selenium RC.
In 2008, Philippe Hanrigou (then at ThoughtWorks) made "Selenium Grid", which provides a hub allowing the running of multiple Selenium tests concurrently on any number of local or remote systems, thus minimizing test execution time.
In 2009, after a meeting between the developers at the Google Test Automation Conference, it was decided to merge the two projects, and call the new project Selenium Web Driver, or Selenium 2.0. After that there was no looking back. Since then new version with updates, bug fixes and supporting more and more OS along with different browsers has made this project a great success.
