As the chair of one of South Africa's largest agencies, Ogilvy and Mather, Nunu Ntshingila is among the highest ranking women in world advertising. Born in Soweto in the 1960s, she learned her trade under Apartheid, when both the working environment and the marketplace were racially divided. Later she had the job of marketing the 'new South Africa' as a tourist destination and has since overseen campaigns for some of the world's biggest brands. Nunu says she moved "from the struggle between black and white to the gender struggle" and talks about her limited ability to change the way black women are portrayed in advertising.

Vasudha Narayanan is the executive creative director at the Lowe Lintas agency in India. Based in Mumbai she says advertising is not an easy job - especially for women - as the unconventional working hours and frequent parties can raise eyebrows in conservative society. Vasudha says she is conscious about the influence her adverts have on society. She says "It's men who need to change their attitudes - we try and encourage men to behave better"
