[Extract] In 2000 the transnational oil giant BP Amoco rebranded itself as "bp: beyond petroleum." The rebranding was part of an effort to portray BP as an energy company, not just an oil company: one that incorporated solar energy in its portfolio and was willing to move away from oil. BP replaced its logo with a vibrant green-white-and-yellow sunburst named after Helios, the ancient Greek sun god. The logo was meant to connote "commitment to the environment and solar power" and promote the new bp "as the supermajor of choice for the environmentally-aware motorist." The lower-case letters were chosen "because focus groups say bp is friendlier than the old imperialistic BP," which stood for British Petroleum.
