The first product, built in a Palo Alto, Calif., garage, was the precision audio oscillator, which used a light bulb as a temperature stabilized resistor in a critical part of the circuit. HP's first client was Disney, which used several of the oscillators in the movie "Fantasia."

In 1968, HP developed the world's first electronic programmable desktop calculator. Next came the HP-35, the first handheld scientific electronic calculator in 1972, followed by the first programmable calculator in 1974.

HP was first to pioneer what are now considered enlightened management practices: management by objectives, stock options for employees, catastrophic health insurance, and open work areas for sharing information. In 1990, HP expanded its computer line, which initially targeted universities, research, and business, to consumers. In 2002, the company bought out Compaq Corp., making HP the world's largest manufacturer of PCs.
