Apple Inc. has purchased a 98-acre property, which will allow the iPad and iPhone manufacturer to nearly double the size of its headquarters in Cupertino, Calif., the San Jose Mercury News reported. Apple, which in the past year reported $65 billion in sales and increased its work force by 12,300 employees, acquired the site from longtime rival Hewlett-Packard Co. “We now occupy 57 buildings in Cupertino, and our campus is bursting at the seams,” said Steve Dowling, an Apple executive. “These offices will give us more space for our employees as we continue to grow.” The purchase price was not disclosed.
