In January 1977, the company registered as Apple Computer, Inc. For several years, Jobs and Wozniak hired a team of computer designers and created a production line. Apple was made public in 1980 for instant financial success. In the following years, Apple supplied new computers with an innovative graphical user interface, such as the original Macintosh in 1984, and Apple's marketing advertising for its products was widely acclaimed by critics.
