Though campaigns against prostitution of children originated in the 1800s, the first mass protests against the practice occurred in the 1990s in the United States, led largely by ECPAT (End Child Prostitution in Asian Tourism). The group, which historian Junius P. Rodriguez describes as "the most significant of the campaigning groups against child prostitution", originally focused on the issue of children being exploited in Southeast Asia by Western tourists. Women's rights groups and anti-tourism groups joined to protest the practice of sex tourism in Bangkok, Thailand. The opposition to sex tourism was spurred on by an image of a Thai youth in prostitution, published in "Time" and by the publication of a dictionary in the United Kingdom describing Bangkok as "a place where there are a lot of prostitutes". Cultural anthropologists Susan Dewey and Patty Kelly write that though they were unable to inhibit sex tourism and rates of prostitution of children continued to rise, the groups "galvanized public opinion nationally and internationally" and succeeded in getting the media to cover the topic extensively for the first time. ECPAT later expanded its focus to protest child prostitution globally.
