Google was founded in 1998 by Stanford grads Sergey Brin and Larry Page. Their business plan was to create an online search engine, but there were already a number of services available online.
Many of the search engines in the late 90's compiled their results by testing the relevance of keywords against related website data. Google ranked their search results based on the number/quality of links to other sites. This laid the basis for much of modern online marketing.
In October 2015, Google Inc underwent significant structural changes. As a result of growth (and in large part due to their Mergers and Acquisitions) the "Google Family" became a holding company called Alphabet.
Alphabet's corporate changes have little effect on the consumer; but provide the corporation with tax benefits, an easier reinvestment environment, and reduced risk to owners.
