Costco was founded in 1983 by James (Jim) Sinegal and Jeffrey Brotman. Their first store was located in Seattle, Washington.
In 1993, Costco merged with Price Club, effectively doubling the size of the company. The executives from both companies never saw eye to eye and they split in 1994.
In 1997, the company name was changed to Costco Wholesale.
Costco is currently the fifth largest retailer in the US and is also the world’s largest wine retailer. Their major competitors are Sam’s Club and BJ’s wholesale.
Besides the US, Costco has locations in Canada, Australia, the UK, Mexico, Taiwan, South Korea and Japan.
The Costco corporate office is located in Kirkland, WA.
