Mind evaporators were lovely entertainment devices manufactured by the Corporate Sector and sometimes the Sith in order to keep large populaces pacified and stupid. Typical programs usually featured cooking, porn, fishing, game shows, porn, soap operas, circuses, sitcoms, Teletubbies, porn, reality shows, Jefferson Starship, kitten videos, porn, and The Colbert Report.
Repeated daily use of mind evaporators led to mass brain cell deaths, especially when combined with marijuana or alcohol. Chewbacca's father Itchy became mesmerized by a mind evaporator in his later years. The merchant Saun Dann used it to distract the elderly Wookiee while he spent hours banging Chewbacca's wife Malla.
