The Texas Instruments calculator is the great, great, grandaddy of hand held calculators. The Texas Instruments calculator was first invented and marketed in 1967 at a cost of $2,500 (that is the equivalent of $16,650 dollars in 2011.) In 1971 the single processor Texas Instruments calculator his the marketplace, dropping the cost of the hand-held calculator into the price range of a consumer product.
In 1972, with the introduction of the TI-2500, the Texas Instruments calculator officially became a consumer product. Priced at $149.95, and later dropped to $119.95, the TI-2500 became a cost effective option to the slide ruler for students and engineers. In 1976 the SR-60 became the first Texas Instruments calculator to offer user programmable functions. The first Texas Instruments calculator to offer scientific notation functionality, the SR-56, was also introduced in 1976.
In 1990 the Texas Instruments calculator with graphing technology was introduced and immediately redefined the role of the calculator in the educational and business communities. Still even today the Texas Instruments calculator is the standard by which all other calculators measure their success in the marketplace.
