A crossover no-one saw coming. That's how many in India are describing Microsoft founder and philanthropist Bill Gates' appearance in an iconic Hindi TV drama with actress and former federal minister Smriti Irani. Mr. Gates appeared on Thursday night's episode of 'Kyunki Saas Bhi Kabhi Bahu Thi' to discuss maternal and child health.

The Gates Foundation has been addressing infant and maternal mortality in disadvantaged states like Uttar Pradesh and Bihar for years. Data shows some improvements in health indicators, but challenges remain in a patriarchal society where awareness is crucial.

'Kyunki Saas Bhi Kabhi Bahu Thi', launched in 2000, drew immense viewership during its original run, focusing on domestic relationships. After a 25-year break, it returned this year to revisit the complexities of family life in modern India.

Gates's appearance has given a new relevance to the series, using its widespread popularity to promote critical health issues. Engaging with Irani’s character Tulsi, Gates emphasized the importance of supporting health and nutrition for expectant mothers. Social messaging has been integrated into the storyline, reflecting modern issues such as divorce and health care.

The four-minute segment where Gates interacts with Tulsi, greeting her in Hindi and discussing family traditions around childbirth, has been widely shared, garnering millions of views online. This unexpected collaboration not only entertains but serves to inspire change, with audiences now more aware of pressing social health issues.
