Rush Limbaugh's apology over the weekend for calling a student a slut and a prostitute wasn't enough to prevent many businesses to stop advertising on his radio show.

The Cleveland Cavaliers are one such business.

Cavs owner Dan Gilbert said over the weekend that he would no longer advertise on Limbaugh's program.

Gilbert is the founder of Quicken Loans, Inc., and announced on his twitter account that the company won't be associated with the show anymore.

Due to Rush Limbaugh's inflammatory comments along w/valuable feedback from our clients & staff, Quicken Loans has suspended ads on his show.

Quicken Loans owns the naming rights to the Cavs arena.

The Cavs flagship station, WTAM 1100, broadcasts The Rush Limbaugh Show, weekdays from 12-3 p.m.

Limbaugh made the derogatory comments about Sandra Fluke, a Georgetown student, who spoke out in support of having health insurance coverage include birth control.

According to the Associated Press, Sleep Train, Sleep Number, Citrix Systems Inc., Carbonite, Legal Zoom and Pro Flowers will also no longer advertise on Limbaugh's program.
