Suggesting and targeting advertising based at least in part on relationships between individuals in a community and monitored activity of the individuals. Advertising may be targeted according to inferred relationships between individuals. For example, if a household is determined to have four members comprising a man and woman much older than two children, it may be inferred that the man and woman are parents, and the parents may be targeted to receive advertising for birthday presents for the children. Targeting may be refined based at least in part on monitored responses to previous advertising. A common access point, such as a home computer or portable device may be used as one means of monitoring individual activity.
