The plan was to have Google purchase Tesla for $11 billion, with Elon Musk maintaining control of the car company for at least eight more years, according to Bloomberg. Tesla had been on the verge of bankruptcy at the time, and it wasn't until the company posted its first quarterly profit in May of 2013 that things started to improve.
Elon Musk had a lot riding on the company, and he only paid himself $1 that year.
Today, however, the company is doing quite well. Tesla Motors is currently valued at $25 billion, and the company has plans for more affordable electric cars and batteries that can power houses. Furthermore, the Tesla Model S sports car will soon have autopilot capabilities.
