It's another list that Warren Buffett can say he tops. At the age of 84, the Berkshire Hathaway chief is the oldest CEO in the S&P 500, according to data provided to CNBC by S&P Capital IQ.
The only other CEO over 81 on the list is Fox's Rupert Murdoch, who also is 84 but a few months younger. Buffett was born August 1930 and Murdoch was born March 1931.
While the two oldest CEOs are among the most famous, the two youngest are, as well. Facebook's Mark Zuckerberg just turned 31 in May, and Yahoo's Marissa Mayer turned 40 a week ago, on May 30. At the beginning of the year, they were the only S&P 500 CEOs still in their 30s. Now it's just Zuckerberg.
Interestingly enough, if you look at the 10 broad corporate sectors, the average CEO age is almost identical—in the mid-50s for all of them.
