Which decade primarily popularized GUI in personal computers, especially by Apple?

The 1980s were pivotal for the popularization of graphical user interfaces (GUIs) in personal computers, especially through the efforts of Apple. During this decade, Apple introduced the Macintosh in 1984, which featured a user-friendly GUI that allowed users to interact with their computers using visual elements like icons and windows, rather than relying solely on text-based commands. This innovation marked a significant shift in computing, making technology more accessible to the general public and setting new standards for user interface design.

Prior to the 1980s, GUIs were largely experimental and primarily seen in specialized settings, such as research labs or universities, where systems like the Xerox Alto had introduced early concepts of GUIs. While the late 1970s saw some advancements in personal computing, it was really the Macintosh's launch in the 80s that brought GUIs into mainstream use on personal computers, shaping user expectations and driving demand for similar interfaces in the industry. The influence of this decade continues to be felt in modern computing experiences today.
