Performers are called "strippers", "exotic dancers", just "dancers", or "entertainers". Strippers are the primary draw for any club. Dancers effectively entertaining customers are the key to generating revenue by keeping customers on site and enticing them to be repeat visitors. The image of strippers (as known today) evolved through the late 1960s and 1970s in the U.S. and international cultures that embraced Americanized striptease; introduced into popular culture by the genre-defining performances of Carol Doda. By the 1980s, the pole dancing and highly explicit imagery associated with today's performers was widely accepted and frequently portrayed in film, television, and theater. "House dancers" work for a particular club or franchise. "Feature dancers" tend to have their own celebrity, touring a club circuit and making appearances. Porn stars will often become feature dancers to earn extra income and build their fan base. High-profile adult film performers Jenna Haze and Teagan Presley, among others, have participated in feature shows through the U.S., as did now-retired stars such as Jenna Jameson.
