Michael Bloomberg started his career as a clerk and worked his way up to head of equity and sales. When his company went public, he used his bonus to start his own company. His innovative idea was to create a single terminal with up-to-date financial information from various sources. This made his company very successful and left competitors behind. As a leader, Bloomberg came up with new ideas that advanced the financial information industry, such as Bloomberg Business Radio and magazines. While an effective leader, it is unclear if he is truly charismatic as the case does not show him having devoted followers.
