One of the many companies that pulled advertising from Rush Limbaugh's radio show said on Wednesday that the decision had hit his business hard, but that he knew it was the right one to make.

David Friend, CEO of Carbonite, made the comments in a call with investors after the company released its second quarter financial results. Carbonite, a software company, was the sixth advertiser to drop its spots on Limbaugh's show in the wake of his infamous comments about law student Sandra Fluke.

At the time, Friend released a statement condemning Limbaugh for calling Fluke a "slut" and a "prostitute" due to her advocacy of birth control.

"No one with daughters the age of Sandra Fluke, and I have two, could possibly abide the insult and abuse heaped upon this courageous and well-intentioned young lady," the statement read in part. "Mr. Limbaugh, with his highly personal attacks on Miss Fluke, overstepped any reasonable bounds of decency."
