This is completely off-topic, but "Big Oil" actually did have a specific historic meaning: it's the descendants of the Seven Sisters, the oil companies party to the Consortium of Iran. Those seven were Anglo-Persian (now BP), Gulf + Standard of California + Texaco (now Chevron), Shell, Standard of New Jersey + Standard of New York (Exxon). By popular convention, Total has sort of slipped into this group despite not being party to the Iran agreement, which obviously undermines the historic meaning of the term.
