ComputerWorld.com, originally Computer World magazine, was the computer technology magazine of choice from the 1960s through the 1990s. Originally the magazine focused on technical issues of interest to technicians, programmers, and managers of very large, very expensive installations of "main-frame" computers and "mid-range" computers that increasingly "ran" large and mid-sized corporations and some military operations as well. Since the late 1980s with the exponential growth and use of "personal computers" the magazine has begrudgingly extended it's coverage into that domain as well.
