Better late than never - just discovered a 2003 resource by UNIFEM: Making a Difference - Strategic Communications to End Violence against Women, available from the UNIFEM site. Apart from lots of practical advice, it includes this amazing story from Eastern Europe:
A billboard campaign in the Czech Republic for Nokia ‘hands free’ telephone accessories showed a man molesting a woman now that his hands were ‘free’ from holding the phone receiver. To protest the ad, the Prague Centre for Gender Studies collected electronic signatures via their website and presented them to the Czech Advertising Standards
Council, the Czech State Administration Office and the Finnish headquarters of Nokia. The letter to Finland stated that this kind of sexist advertising contradicts Nokia’s brand identity. Within 14 days of receiving the letter, the Finns withdrew the billboard.
