Marketing
The game production has similar distribution methods to those of music and film industries.
The publisher's marketing team targets the game for a specific market and then advertises it. The team advises the developer on target demographics and market trends, as well as suggests specific features. The game is then advertised and the game's high concept is incorporated into the promotional material, ranging from magazine ads to TV spots. Communication between developer and marketing is important.
The length and purpose of a game demo depends on the purpose of the demo and target audience. A game's demo may range between a few seconds (such as clips or screenshots) to hours of gameplay. The demo is usually intended for journalists, buyers, trade shows, general public, or internal employees (who, for example, may need to familiarize with the game to promote it). Demos are produced with public relations, marketing and sales in mind, maximizing the presentation effectiveness.
