In-Game advertising is defined as the "inclusion of products or brands within a digital game." The game allows brands or products to place ads within their game, either in a subtle manner or in the form of an advertisement banner. There are many factors that exist in whether brands are successful in the advertising of their brand/product, these being: Type of game, technical platform, 3-D and 4-D technology, game genre, congruity of brand and game, prominence of advertising within the game. Individual factors consist of attitudes towards placement advertisements, game involvement, product involvement, flow, or entertainment.
