The Department of Economic Development has revealed how much it's making from trademarking the TT brand.
3FM submitted a Freedom of Information request to the department asking for the figures for the past five years.
In recent months the department's found itself embroiled in rows with a number of Island organisations over charges for using the TT initials.
Now, it's revealed it's made almost £3.6 million since 2012.
The DED's responded to 3FM's request by providing figures for each of the past six financial years.
Licensing the TT trademark raised just under £250,000 between April 2011 and March 2012 - a figure that more than doubled the following year.
The amount grew steadily until 2015/16, when it leapt to £813,000 and then last year reached a peak of more than £878,000.
In the House of Keys next week, Ayre and Michael MHK Tim Baker will ask questions about the department's licensing policy.
