Google Inc. is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, and software. Most of its profits are derived from AdWords, an online advertising service that places advertising near the list of search results.
As of September 2013, Google operates 70 offices in more than 40 countries. Google celebrated its 15-year anniversary on September 27, 2013, although it has used other dates for its official birthday. The reason for the choice of September 27 remains unclear, and a dispute with rival search engine Yahoo! Search in 2005 has been suggested as the cause.
