Ronnie Screwvala: The cable guy

Ronnie Screwvala changed the viewing habits of the world’s most populous country, India - but he started out selling toothbrushes. BBC business editor Simon Jack and journalist Zing Tsjeng chart his journey, from knocking on apartment doors in 1980s Mumbai selling cable TV, to building a media empire that would transform Indian entertainment. Ronnie Screwvala launched the first Indian daily soap opera, the country’s most popular children’s channel, and a Hollywood-style film studio in Bollywood. He rode India’s economic liberalisation to reshape how a nation watched television and movies. Along the way he made big deals with Rupert Murdoch and Disney. And his most recent business move into ed-tech made Ronnie Screwvala a billionaire.

Larry Ellison: Winning the database wars

Larry Ellison’s business mantra is simple: “It is not sufficient that I succeed — everyone else must fail.” From humble beginnings as an adopted child in Chicago to becoming one of the richest men in history, BBC business editor Simon Jack and journalist Zing Tsjeng trace the relentless ascent of one of Silicon Valley’s most combative and controversial figures. After recognising the commercial potential of databases, Larry Ellison founded Oracle in the 1970s and spent the next two decades driving an aggressive sales culture that fuelled meteoric growth — and nearly sank the company in an accounting scandal. But Larry Ellison rebuilt his company into a global enterprise software giant, and in recent years has extended his influence beyond technology into Hollywood. All while amassing fighter jets, yachts, and even a Hawaiian island.
