No, the ACTUAL question is, "Has Campbell ever run advertising for Icon?" Just because there's advertising on ANN doesn't mean the company is paying for it or ever paid for it. Note the five lawsuits in the 2000s, where Campbell claimed companies violated a supposed verbal contract to advertise. Note, also, that Campbell made the same claim regarding Cirrus a few years back.
In the Cirrus case, Campbell claimed (online) that Cirrus owned him $700,000 for unpaid advertising. In the written agreement about the plane, Cirrus expected $5,500 a month payment. Campbell claimed that advertising was supposed to cover that. Campbell's claim of an unpaid $700,000 bill meant that he'd run free advertising for them for over ten years.
So if there had been Icon advertising on ANN, that doesn't mean there was an agreement...other than being nice to Campbell. The Cirrus case is a classic example of what happens when a company stops being Jim Campbell's friend.
Read the Icon agreement, come to your own conclusions. But don't believe anything Campbell says about "private sources say..." or "industry insiders report...."
