A couple of weeks ago, we published an infographic showing how the list of the most valuable companies in the U.S. has changed drastically over the last 100 years.

Near the top of that list in 1917 is The Standard Oil Company of New Jersey, which is just one of the 34 forced spin-offs from the original Standard Oil juggernaut that was split up in 1911.

In today’s chart, we look at the “fragments” of Standard Oil, and who owns these assets today.

MONOPOLY DECISION

At the turn of the 20th century, John D. Rockefeller’s Standard Oil was a force to be reckoned with. In the year 1904, it controlled 91% of oil production and 85% of final sales in the United States.

As a result, an antitrust case was filed against the company in 1906 under the Sherman Antitrust Act, arguing that the company used tactics such as raising prices in areas where it had a monopoly, while price gouging in areas where it still faced competition.

By the time the Standard Oil was broken up in 1911, its market share had eroded to 64%, and there were at least 147 refining companies competing with it in the United States. Meanwhile, John D. Rockefeller had left the company, yet the value of his stock doubled as a result of the split. This made him the world’s richest person at the time.

RESULTING COMPANIES

The company was split into 34 separate entities, mainly based on geographical area.

Today, the biggest of these companies form the core of the U.S. oil industry:

But that’s not all – the Standard Oil asset portfolio also carried some other interesting brands that you’d recognize today:
