There are several types of media advertising including print, outdoor, broadcast, covert, surrogate, public service, and celebrity advertising. Print advertising includes newspapers, magazines, brochures and fliers. Outdoor advertising uses billboards, kiosks, and events. Broadcast advertising is on television, radio, and the internet. Covert advertising subtly features brands in movies and TV. Surrogate advertising promotes related brands when direct advertising is banned. Public service advertising raises awareness for social causes. Celebrity advertising uses popular figures to endorse products.
