Business-savvy Oprah transformed her fame from The Oprah Winfrey Show, which ran for an impressive 25 years, into a mammoth business and media empire. The first Black female to achieve billionaire status, Winfrey is today worth an incredible $2.6 billion (£2bn).

The media queen's entrepreneurial prowess first began to emerge in 1986, when she founded multimedia production company Harpo Productions. In 2011, she launched the cable television channel Oprah Winfrey Network (OWN), and her 25.5% stake is worth more than $65 million (£49.2m) according to Forbes.

Winfrey also has a 7% share in Weight Watchers and signed a multi-year deal with Apple TV+ in 2018 to produce original content for the streaming giant.
