Answer:
Kodak is using ambush marketing and guerrilla marketing.
Explanation:
Ambush marketing is where a business tries to associate itself with an event that is officially sponsored by a rival business. The beach volleyball tournament has Fuji film as its official sponsor. However, a direct competitor, Kodak, begins marketing its products outside the venue, thus benefiting from the event even though Fuji film paid a huge amount in its sponsorship. This is a classic example of ambush marketing.
Guerrilla marketing involves the use of unconventional or unusual methods to promote a product. Kodak adopts this technique by having its employees paint their entire bodies yellow to draw attention. Moreover, Kodak offers rewards to people for taking the goofiest pictures, again employing an unconventional technique to promote Kodak cameras.
