Murdoch began her career as a manager of programme acquisitions at her father's FX Networks, a cable television unit based in Los Angeles. Operating as EP Communications, on 22 September 1994 Murdoch and her then-husband, Elkin Kwesi Pianim, purchased a pair of NBC-affiliate television stations, KSBW and KSBY, in California on a US$35 million loan secured by her father. Within 18 months, the couple reorganised and sold the stations at a $12 million profit. Murdoch moved with Pianim to the United Kingdom where Rupert Murdoch was running BSkyB after forcing a 1990 merger with BSB. The early years of BSkyB saw a haemorrhage of cash from Murdoch's News Corporation funds. To help turn around the financial fortunes of the company, New Zealand television executive Sam Chisholm was brought on board to manage the day-to-day operations and build the subscriber base, with Elisabeth Murdoch as his second-in-command and de facto apprentice. By the time Chisholm left the company, BSkyB was the most profitable company in the United Kingdom. As managing director, Elisabeth oversaw BSkyB's £12 million sponsorship of the troubled Millennium Dome, to the relief of its Cabinet overseer, Peter Mandelson. However, she also faced criticism after brokering her father's failed £623.4 million bid for England's champion Manchester United team. After quarrelling publicly with Chisholm, she ventured out on her own as a television and film producer in London. She advocated Sky setting up a film and production unit similar to BBC Films and Film4 Productions. However, due to lack of success, this unit closed down, and she founded Shine Limited in March 2001, with 80 percent ownership retained by herself, 15 percent by Lord Alli, and five percent by BSkyB. BSkyB signed a deal guaranteeing to buy an agreed amount of Shine programming for two years. In 2011, Shine was acquired by News Corporation in a controversial deal that raised questions about nepotism. In February 2013 Elisabeth was assessed as the fifth most powerful woman in the United Kingdom by Woman's Hour on BBC Radio 4. Elisabeth Murdoch is now Executive Chairman of the global TV and film production and development company, Sister, which is headquartered in London with offices in Los Angeles.

In 2017, Murdoch married artist Keith Tyson. Murdoch is a dual national of the United States and the United Kingdom. Murdoch currently resides in the St John's Wood neighbourhood of London.
