A 1958 article in Harvard Business Review referred to information technology as consisting of three basic parts:
i. Computational data processing
ii. Decision support
iii. Business Software
in fact, this article probably coined the term.
Over the ensuing decades, many corporations created so-called "IT departments" to manage the computer technologies related to their business. Whatever these departments worked on became the de facto definition of information technology, one that has evolved over time.
Today, IT departments have responsibilities in areas like computer tech business software deployment, and information security.
Especially during the dot-com boom of the 1990s, information technology also became associated with aspects of computing beyond those owned by IT departments. This broader definition of IOT includes areas like software department, computer systems architecture, and project management.
