I read Titan. Interestingly, it documents how SO's market share was declining steadily throughout the anti-trust trial, and Rockefeller was unable to stop it.

It runs against the conventional story of SO being an inevitable monopoly.

Well, at the time, the kerosene market was declining and there was nothing bringing it back. Right after the breakup, Henry Ford finally perfected the automobile, and Standard Oil came right back.

Market share isn't the same thing as market size. The point being, SO was losing to competitors.

Very true. From 1870 to 1890 SO was 90% of the oil market. By 1907 they were 68%.

Their main competition was from Russia oddly enough.
