In this paper, the authors address a literature gap with regard to sponsorship outcomes of mega-events and their host countries. This paper is about research that investigates the interrelatedness of three important images-host country, mega-event, and sponsor images-from the perspective of a cameo appearance building on the sponsorship and brand placement literature. It is based on the premise that the host city makes a cameo appearance during a mega-event for sport tourists while the event itself makes a cameo appearance for residents of the host country. The results indicate that mega-events can have a transitory influence, and that cameo effects exist, but that the patterns of relationships are different for sport tourists and residents.
