The franchise that would become the Giants was established in 1883 in New York City and was initially known as the Gothams. In 1885 the team changed its name to the Giants, which was supposedly inspired by a description of the squad by its proud manager in the wake of an extra-inning victory.

In spite of winning the World Series in 1954, the team could not draw fans as consistently as their Brooklyn rivals did. Owner Horace Stoneman thought the relocation to San Francisco would revitalize the team, but they continued to suffer from inconsistent play and attendance even after the move.

The Giants have won six pennants, and the World Series in 2010, 2012 and 2014 since arriving in San Francisco.

The San Francisco Giants of Major League Baseball originated in New York City as the New York Gothams in 1883 and were known as the New York Giants from 1885 until the team relocated to San Francisco after the 1957 season.
