Compared to 1992, the changes in Forbes's 400 list of 1993 were even greater.
Last year's number one richest man in America, Bill Gates, was overtaken by someone else this year.
The magazine in Dean's hands provided a fairly detailed introduction to each of the top ten.
This year, taking first place was Buffett, whose stake in Berkshire Hathaway had brought his net worth to 8.3 billion US dollars.
This figure had nearly doubled compared to last year, with his ranking having soared from eighth to first.
The reason for Buffett's net worth to have doubled was mainly due to the soaring stock price of Berkshire Hathaway.
At its peak, the increase was as high as 70%, along with other investments, Buffett easily doubled his assets.
However, even though he had a wealth of 8.3 billion dollars, Buffett stated that his assets would be inherited by his own charitable foundation.
