Targeted or other advertising may comprise one or more advertisements presented in a virtual world environment constructed according to consumer parameters, with the advertisements presented according to rules, scripts, or other parameters defined by the advertiser(s). For instance, one or more consumer computing device(s) can access data defining a brand name, logo, and/or message and can access data defining consumer preferences for the context in which advertisements are to be presented. For example, the context may vary according to viewer identity, programming content, time of day, and the like. Then, the consumer computing device(s) can render a virtual world based on the consumer preferences with the virtual world also comprising the advertisement(s) generated based on advertiser definitions.
