The piece includes a list of the 50 largest of 1917, ranked by assets. Here are the top 15:

When I look at lists like this I'm never quite sure if I'm supposed to be amazed by how much has changed or by how much has stayed the same. The top three of 1917 are still with us, after all. U.S. Steel Corp. is of course much diminished, but AT&T Inc. and what is now called Exxon Mobil Corp. (Standard Oil of New Jersey changed its name to Exxon in 1972, No. 15 Standard Oil of New York changed its name to Mobil in 1966, and the two merged in 1999) are among the biggest, most powerful, most valuable U.S. corporations of 2017. So are No. 8 DuPont, although it recently merged with rival Dow to become DowDuPont Inc., and No. 11 General Electric Co.
