The field of information technology has steadily evolved since the early 1980s. Epstein (2011) defines information technology as “the use of computers and software to manage information.” In the business world, the information technology department is responsible for storing, protecting, processing, transmitting, and retrieving digital information (Epstein, 2011).
In the early 1980s, computers that operated with integrated circuits on a single chip became more affordable and were specifically designed and targeted to consumers (Epstein, 2011). Graphical user interfaces, which allowed users to use screens with windows, clickable controls, and colors, became available toward the end of the decade. Popular operating systems, such as Windows and Apple, also became available during the 1980s.

Memory capabilities in computers have also evolved over time. 24 megabytes of RAM was considered a substantial amount of memory fifteen years ago. Today, most new computers boast one gigabyte of available memory.
The focus of information technology has shifted with these advancements. Instead of focusing on the capabilities of a single computer, the field of information technology now focuses on networking computers together. Epstein (2011) states that this advancement has impacted organizational practices in the world of business. For instance, networks allow a variety of employees to gain access to business records held in company databases. As a result, the software that is required to maintain these databases has become a billion-dollar industry (Epstein, 2011).
The evolution of information technology has also changed how business is conducted on the world-wide level. The advent of customer relationship management software now drives business practices for companies selling products to customers all over the Earth (Epstein, 2011).
One of the most far reaching developments in the information technology field is the internet. Epstein (2011) states that the internet is now the primary choice of communication for many people. Email and instant messaging platforms have become popular methods for staying in touch. In terms of business, the internet now serves as an international advertising podium. The capabilities of social networking have allowed businesses to reach new and existing customers in ways that were unimaginable before.
The evolution of information technology has also affected the business of banking. Daily, time-consuming trips to the bank were once the norm for businesses. The advent of online banking now allows both individuals and businesses to keep tabs on their finances with the click of a button.
The advancement of cellular phones has also impacted the business world and society as a whole. The introduction of the smart phone created an entirely new world of interpersonal connection. Employees now have constant access to business emails and records, making them almost constantly reachable.
In conclusion, it is evident that the field of information technology is constantly evolving. Each step in this evolutionary process continues to affect society, from creating social networks that include individuals from all corners of the world to simplifying and streamlining business and banking practices.
