The founder and former CEO of CNN is responsible for the 24-hour cable news cycle, which revolutionized the way the world consumes information, particularly breaking news.

The first successful person-to-person selling platform of its kind, eBay gave people a way to sell new and used items to people far and wide.

Net worth: $100 billion at the time of his death
How he changed the way we live: Sam Walton founded the Walmart stores. The chain has a market cap of $221.1 billion and is still No. 1 in sales both in the U.S. and across the world.
Walton opened a small store in Arkansas with the idea to draw customers by offering the lowest prices on goods. He followed 10 signature rules for building a business, which included profit-sharing, controlling expenses for the store and the consumer and defying conventional wisdom.
The strategy worked for Walton, who created one of the most successful business models of all time and revamped the in-store retail experience for consumers around the globe. Today, the Waltons are the richest family in America, with a combined net worth of $130 billion.
21. Arianna Huffington, Huffington Post

He fired all the managers so employees could supervise themselves and offered workers one month’s salary to quit if they didn’t love their jobs. He also spent $350 million of his own money on revitalizing Downtown Las Vegas, where Zappos is headquartered.
Quirky and eccentric, Hsieh lives in a 240-square-foot trailer despite his massive fortune. His roommates are two alpacas.
