Answer: D, BackRub
While the company has always been called Google, the search engine that launched the tech giant on its way was originally known as BackRub when Sergey Brin and Larry Page created it at Stanford in 1996. In 1997 they changed the name to Google – a misspelling of Googol, a very large number (1 followed by 100 zeros).
(If you chose "PageRank," give yourself partial credit: That's the name of the algorithm that underlies Google's search results. And yes, it was named after Larry.)
