It would seem that social media platforms in India -- from Facebook and Twitter to YouTube and WhatsApp -- are going the way of the ultrasound machine. The ultrasound machines, used to detect foetal abnormalities and life-threatening conditions that affect the abdomen, heart and other internal organs, were introduced into India with the intention to save lives and cut medical costs. Yet, within a few years, in India, they were being widely used to detect the gender of a foetus, leading to large drops in sex ratio. The ultrasound machine's pervasive misuse also invited a slew of laws tailored to prevent this.
