A buoyant Hull City ended Blackburn Rovers' 10-match unbeaten run with three points to celebrate the announcement of the club's takeover by the Acun Medya Group.
George Honeyman found the back of the net after just eight minutes for the hosts to give them an early lead.
Ben Brereton Diaz had a penalty appeal turned down for the visitors after he was pushed over in the box, while Reda Khadra had a long-range shot saved.
Blackburn piled on the pressure after the break, but Tom Eaves' header doubled Hull's lead midway through the half to secure the victory.
