Costco was founded in 1976 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 was the first company to reach $1 billion in sales in less than 6 years.
In 2017, the company had annual revenue of $129 billion. That same year, the company was named America’s Best Employer by Forbes.
Costco is being urged by many to remove a children’s book called No More Poems since many feel it contains a “poem” about how to kill your sibling in a variety of ways.
Besides the US, Costco has locations in Canada, Australia, the UK, Mexico, Taiwan, South Korea, and Japan.
The Costco corporate office is located in Issaquah, Washington.
