Edison International's corporate history is composed of more than two hundred mergers, acquisitions and start-up companies going back to 1870. The origin of the Edison name can be traced to the 1897 creation of the Edison Electric Company of Los Angeles, which in 1909 became Southern California Edison. Parts of the electric distribution system were sold to the City of Los Angeles Department of Water and Power in 1922 and 1939. In the early part of the 1900s, the flat oval symbol came into common use as the first graphic signature of the company.

In the 1930s, a new logotype was created emphasizing the Edison name with a lightning bolt. This logo was used until the late 1950s when a new symbol was instituted: the letters SCE in the shape of a common household appliance plug.

In the 1980s, the design took a new slant, literally, as the "plug" logo was redesigned and earth tone color bars added. At about the same time, SCEcorp was created as the holding company for SCE and a group of non-utility subsidiaries collectively named the Mission Group.






With deregulation of California's electric utilities looming, and huge growth in the non-utility sector of the business, SCEcorp changed its name in 1996 to Edison International. A new system of company logos was created to tie all subsidiaries together into one common brand, the now familiar "sunburst."

Over the last century, the transformation of the Edison logo has kept in step with the company's businesses. Once a regional leader, today Edison International companies conduct business all over the world. The reputation the company has established as a leader in Southern California helps Edison International to build a global reputation. This reputation, or Edison brand, provides a valuable contribution to the continued success of Edison International.

These logos continue to represent a company that delivers reliable electricity to Southern California.
