Advergaming refers to advertising through games. It began in the 1970s with simple in-game ads and has evolved with technology. There are two main types: in-game advertising, which embeds ads directly into games; and advergames, which are full games created specifically for advertising. Both can increase brand awareness and memorability but must be implemented carefully to avoid negatively impacting attitudes. The mobile/social game market is growing rapidly and offers many opportunities for innovative advergaming strategies.
