Abstract: A modular advertising or display insert, module or replacement lid to a water cooler provides a display panel or image for viewing by a person getting water at or passing by the water cooler. The display panel may be a back-lit photograph or transparency, a flat or curved screen monitor or the like. The monitor may be remotely controllable via a modem or other remote communication means for remote changing of the pictorial image on the monitor. The display module is constructed to mount to the water cooler housing and to fit in place to maintain the design lines of the existing water cooler. The display module may be placed on a water cooler retroactively, after the water cooler has been placed at a targeted or desirable location, or may be incorporated onto a water cooler prior to placing the water cooler at the targeted or desirable location.
