Texas Instruments TI-84 Plus graphing calculator

The TI-84 Plus is one of the most iconic graphing calculators used worldwide, particularly in secondary and higher education for mathematics and science. It was introduced by Texas Instruments and has since become a standard tool for standardized testing and classroom learning.

Texas Instruments (TI) is a legacy American technology company founded in 1930, originally focusing on seismic exploration and defense electronics before revolutionizing the semiconductor and consumer electronics industries. While the brand remains headquartered in Dallas, Texas, its consumer electronics and calculator hardware are manufactured through global supply chains, primarily in China and Southeast Asia.

Ownership of the brand has remained consistent with Texas Instruments Inc. Throughout its history, the company has managed its own Education Technology division, which oversees the development and distribution of the TI-84 series and its subsequent color and CE iterations.
