To succeed in the U.S. economy, companies must constantly adapt to changing conditions. Though some of the nation’s largest corporations — companies such as General Electric, Exxon Mobil, and Walmart — have always dominated their industries, for many American consumers the landscape of companies has shifted over the course of their lifetimes. 

To identify the largest companies in the year you were born, 24/7 Wall St. reviewed annual revenue figures for companies on the Fortune 500 each year from 1955 through 2020. General Motors was the nation’s largest company throughout the 1950s, ‘60s, and part of the ‘70s. The company now known as Exxon Mobil edged out the automaker in 1975, but GM returned to the No. 1 position periodically in subsequent years. 

Since 2001, either Walmart or Exxon Mobil has occupied the top spot. While Exxon Mobil took a hit in 2020 because of the pandemic, and was not among the top five largest companies,  Walmart reported revenue of over $520 billion in its most recent fiscal year. The global retailing giant is the world’s largest company by revenue — and the largest employer in 18 states.

Though industrial companies used to be among the largest in terms of revenue, internet and tech giants like Alphabet, Apple, and Amazon are decisively making their way toward the top of the list.

These large companies tend to pay their executives well and have some of the highest paid CEOs in the country.

Methodology

To determine the biggest company the year you were born, 24/7 Wall St. reviewed annual revenue figures for companies on the Fortune 500 each year from 1955 through 2018. We also reviewed data from company press releases and SEC financial filings. It should be noted that listed company names came directly from Forbes, and so Forbes’ naming convention is used in all cases as the current name of the company. The company listed as Exxon Mobil from  1999 onward was named Exxon Corporation from 1972 through 1999 and Standard Oil Company of New Jersey prior to 1972
