Oprah Winfrey’s influence extends to her business ventures as well. In 2011, she launched the cable channel OWN (Oprah Winfrey Network) in partnership with Discovery Communications. Despite initial struggles, the network eventually found success with hit series like “Queen Sugar” and “Greenleaf.” Oprah has also invested in Weight Watchers, becoming a significant shareholder and playing a key role in the company’s restructuring.
