The early practice of CI can be traced back to 19 14, which was initiated by AEG Electric Company of Germany. AEG adopted the trademark designed by Peter Behans for the first time in its electrical products, which became the embryonic form of unified visual image in CI. Then, from 1932 to 1940, Britain implemented the London underground project, which was headed by Frank Bi Ke, chairman of the British Industrial Design Association, and was called the classic of "design policy".

Words were born.

After World War II, the international economy recovered, and business operators felt the importance of establishing a unified identification system and shaping a unique business philosophy. Since 1950, major enterprises in Europe and America have introduced CI. From 65438 to 0956, based on corporate culture and corporate image, American International Business Computer Company highlighted the spirit of manufacturing cutting-edge scientific and technological products, and designed its full name as blue "IBM" with a sense of quality and times. This is even if the standard stereotyped writing becomes the image representative of "blue giant" in the next forty years, it is synonymous with "avant-garde, science and technology, wisdom"; It is also an important symbol of the formal birth of ci. Since the 1960s, there has been a trend of enterprise CI directors in Europe and America. The representative work in the 1960s was RCA, which expanded from the radio industry to eight fields, such as information and entertainment. The representative works in 1970s are the symbol of Coca-Cola, with strong red impact, unique bottle shape and rhythmic stripes. In short, the sixties and eighties were the heyday of CI in Europe and America. Japanese enterprises began to create their own CI after 70 years, and China enterprises began to create their own CI after 90 years, thus making it a worldwide trend.
