1978 -- BATUS, Inc., the U.S. division of BAT Industries, (British American Tobacco) PLC, purchased an 80 percent stake in the Kohls Food and Department Stores and took complete control of the company. At that time, the Kohl family withdrew from the operations of the company. Source.
I'll concede that I got it wrong since the Kohl family has not run the company in 30 years. This still likely won't curtail your boycott.
