Advertising artificial intelligence (AAI) are a mass-produced form of terran-designed artificial intelligence. In service by 2478, they are a fairly common sight on the streets of well established planets such as Tarsonis. As their name suggests their primary function is to advertise goods and services. They can be privately employed by shop owners, set up in public areas for general advertisement and mounted in roving robots, moving from one potential buyer to another. These robots can be remotely controlled by an external AI.
