What does BP actually stand for?

BP actually stands for several different things depending on historical and current context, with original and modern meanings. Historically, BP actually stood for British Petroleum, founded in 1908 as Anglo-Persian Oil Company, later becoming British Petroleum Company in 1954, and was state-owned British oil company. In 1998, British Petroleum merged with Amoco and became BP Amoco, then in 2001 rebranded to just BP, with slogan Beyond Petroleum to reflect move beyond oil to renewable energy, so officially company is now just BP plc, not British Petroleum, though many still call it British Petroleum. So BP actually stands for nothing now officially, it is just BP, but historically it stood for British Petroleum. In other fields, BP actually stands for blood pressure in medicine, which is force of blood against artery walls. In business, BP actually stands for business plan, business partner, or business process. In building products, BP actually stands for Building Products, as in BP Building Products Canadian shingle manufacturer in LaSalle, Quebec owned by Saint-Gobain. In education, BP actually stands for Bachelor of Pharmacy. In chemistry, BP stands for boiling point. In finance, BP stands for basis point. In retail, BP stands for Brass Plum clothing line. So what BP actually stands for depends on context, but historically most famous is British Petroleum, now just BP, and in medical most common is blood pressure.
