NEW YORK (AP) — A plaque that reads “Birthplace of ‘Silicon Valley'” marks the garage in Palo Alto, California, where Hewlett-Packard Co. got its start in the late 1930s.

Bill Hewlett and Dave Packard became friends studying engineering at nearby Stanford University. At a time when working for larger corporations was much more common, the pair formed their own technology company at the encouragement of a former professor.
