IBM Punch Card Sets Standard
The key company behind the formation of IBM was the Tabulating Machine Company, which invented punched-card data processing. C-T-R advanced the technology in 1923 with the first electric key punch, a speed and accuracy advance over mechanical punches. In the late 1920s, IBM introduced an 80-column punch card--think of it as a higher-density storage device. The "IBM Card" became the industry standard.
