The strip club as an outlet for salacious entertainment is a recurrent theme in popular culture. In some media, these clubs are portrayed primarily as gathering places of vice and ill repute. Clubs themselves and various aspects of the business are highlighted in these references. "Top Strip Club" lists in some media have demonstrated that U.S.-style striptease is a global phenomenon and that it has also become a culturally accepted form of entertainment, despite its scrutiny in legal circles and popular media. Popular Internet sites for strip club enthusiasts also have lists calculated from the inputs of site visitors. The legal status of strip clubs has evolved over the course of time, with national and local laws becoming progressively more liberal on the issue around the world, although some countries (such as Iceland) have implemented strict limits and bans. Strip clubs are frequent targets of litigation around the world, and the sex industry, which includes strip clubs, is a contentious issue in popular culture and politics. Some clubs have been linked to organized crime.
