Your question has many possible answers but I will try to answer the one I believe you are after.
What is 'Oprah Winfrey' leadership, as in if you used it in a sentence. Gordon Brown doesn't have 'Oprah Winfrey' leadership.
What it comes down to is Authority and how you gain it. Oprah Winfrey's opinion is respected because people believe she is speaking with authority. That is from or of a position of authority where a person knows what they are talking about. Max Weber theorised that there was three types of Authority, Tradition - For example a king inherits authority because his family have ruled for decades, Rational - Someone elected has rational or legal authority because people chose to vote for them, Charisma - This is the ability to charm or beguile people with your personality a great example of this would be John F. Kennedy or Barack Obama.
Charisma or the ability to be Charasmatic is the method Oprah Winfrey uses to gain Authority and with Authority she exercises leadership and subsequently power.
