Some Like It Hot

Playboy magazine’s “History of the Sexual Revolution,” a 10-part series that began in December, has inspired $25 tours of New York’s landmarks to sex. Above, a group drops by Times Square, home in the early 20th century to the Ziegfeld Follies and then to a host of shocking shows and shops. But after years of tawdry decline, Times Square is being redeveloped with hotels, yuppie theme bars and fine restaurants. Proceeds of the tours go to the National Campaign for Freedom of Expression, a nonprofit organization dedicated to preserving First Amendment rights.
