The term 'overpublicizes' means to excessively promote or advertise something. This can be done in a variety of ways, such as ballyhooing (9 letters) and hyping (5 letters). Ballyhooing is a form of advertising that uses exaggerated claims and sensationalism to draw attention to a product or service. Hype is similar, but it is more focused on creating excitement and enthusiasm for something. Both of these tactics are used to overpublicize a product or service.
