I may be totally wrong on this point, but as a font snob, when I see any game show use Arial, or god forbid Times New Roman, on their show for any purpose, I assume that laziness is the reason why. I hadn\'t considered the licensing involved.
I remember the dustup when Ikea moved from Futura to Verdana, and I remember reading that cost-saving was the main issue, but I still don\'t really understand why that is - Futura seems to have been around for at least 80 years.
