The Billboard Liberation Front practices culture jamming via altering billboards by changing key words to radically alter the message, often to an anti-corporate message.{{cite news |title=Using urban guerrilla tactics, Billboard Liberation Front 'adjusts' ads |url=https://www.sfgate.com/living/article/Massaging-the-message-Using-urban-guerrilla-2593898.php |newspaper=SF Gate |date=August 24, 2003 |access-date=2010-12-09 }} It started in San Francisco in 1977.{{cite news |author=Alexander Barley |title=Battle of the image |url=http://www.newstatesman.com/200105210037 |newspaper=New Statesman |date=May 21, 2001 |access-date=2010-12-09 }}

Advertising executives informed Jill Posener, author of Spray it Loud (1982), that the executives designed billboards to attract attacks because the changes drew attention to the products. The BLF were aware of this possibility and considered invoicing advertisers including Chiat Day for the BLF's work.{{cite book
