HD Radio launches Motown effort When HD Radio wanted to impress the automotive industry designers and engineers at the North American International Auto Show in Detroit, our team went into overdrive. Our brand ambassadors jumped on the People Mover in Detroit during the two-day Industry Insider “Spy Day” at the auto show. Decked in HD Radio orange, our 15 member team handed out over 21,000 VIP lanyards to those attending the show. Those with VIP passes were instructed to a “Detroit” themed landing page on the HD Radio Web site to win HD Radio converters. Our mobile assault continued with a caravan of 5 two-sided mobile billboards traveling the COBO Center area on the weekends to build brand awareness.
