A lawsuit brought against Facebook for sexist job advertisements exposes the discriminatory nature of the online marketing

In September, a group of people searching for work in the US filed charges against Facebook and 10 other companies for discriminating against women by targeting certain job advertisements only at men. The employers, from sectors such as labouring and lorry driving, had used Facebook’s ad-targeting tools to direct the opportunities at those they thought most suitable – and this did not include women. Although the outcome of the case has not yet been decided, it could – along with similar cases – have a seismic impact on the future of digital advertising and, consequently, on the future of the net.
