 Some websites use 1926 as the founding date when Herbert Bell was an executive with Jackson Bell Company, Los Angeles, California.
 In 1986, Israeli investors bought the brand from Teledyne, in order to name their newly formed personal computer manufacturing company producing discount computers in the United States and Canada.
 In 2000, Packard Bell, which in the late 1990s had become a subsidiary of NEC, stopped its North American operations while in the mean time expanding overseas and became a leading brand in the European PC markets.

 Gateway products are now sold in the Americas and Asia, while Packard Bell products are sold in Africa, Europe and the Middle East.
