A global celebrity on the other hand is someone who is known by most people or is a mainstream celebrity. Such celebrities are also known as either a household name or superstar.
For example, Virgin Director Richard Branson was notable as a CEO, but he did not become a global celebrity until he attempted to circumnavigate the globe in a hot air balloon and generate publicity for himself. Another high profile categorisation of celebrity status is the A-list, based on the marketability of celebrities.
