Embodiments of the present invention relate to providing low-cost message display boards to users of a message display board service. According to one embodiment of the present invention, display boards capable of displaying a user designated message are supplied by a provider of a message display board service for free or for a very low cost. The user may then use the display board to display personalized messages designated by the user. In exchange for use of the low-cost or no-cost display board, the user accepts that the display board is adapted to receive periodic, supervening messages from the service provider that will be temporarily displayed on the display board in place of any user designated message. The supervening messages transmitted by the service provider may be advertising messages supplied by the service provider or one or more third party advertisers who pay a fee to the service provider in exchange for the display of the ads on display boards of the users.
