Interactive wagering system with promotions

An interactive wagering system is provided that promotes wagering to users at user equipment. The user equipment may be based on a set-top box and television, a personal computer, a cellular telephone with a display, or other such devices. Wagering may be promoted by notifying the user of an opportunity to place a wager on a given race. Wagering may also be promoted by providing the user with an on-screen opportunity to sign up for a wagering television channel or interactive wagering service. The on-screen promotions that are displayed to the user may be targeted based on the television programming that is being displayed or the user's interests. The user's activities may be monitored to collect information on the user's interests. If a particular race or the like is being discussed during a television program, the user may be provided with an opportunity to wager on that race.
