DC Comics is a division of Warner Brothers Entertainment and an American comic book. The initials "DC" stood originally for the company's title Detective Comics, and later became the official name. The first DC Comics logo was introduced in 1940. The small logo read simply, "A DC Publication". The November 1941 DC titles brought out a new version, which was the first DC logo to have a white background. By November 1949, the circular logo was updated to comprise the company's formal name - National Comics Publications. DC Comics decided to retire the circular emblem in October 1970 in favor of a simple "DC" in a rectangle with the star of the book or the name of the title. The initials "DC" appeared in a block-like typeface that would remain through later logo revisions. However, in 2005 the publisher of Batman, Superman and Wonder Woman decided to replace the old, flat, four-star bullet logo that has been on the covers of DC Comics since the mid-1970's. The new logo - "DC" letters against a Saturn-like ring in a dimensional rendering, with a single star - obsolesces the longstanding, Milton Glaser-designed icon. The move was considered "part face lift and part marketing strategy." The first comic book with the new symbol came out in stores on May 25, 2005.
