The TI-84 Plus series is a line of graphing calculators produced by Texas Instruments. They are ubiquitous in the American education system, and have historically been considered the de facto standard in grade school math. The series has also amassed a significant hobbyist following, along with a large library of community-developed applications, for its support of assembly language and TI-BASIC programs.
The family was superseded by the TI-84 Plus CE series in 2015; of the original series, only the TI-84 Plus is still in production, the Silver Edition and C Silver Edition having been discontinued that same year. However, they remain popular in the United States, with the TI-84 Plus being issued by schools more than 20 years after its introduction.
Beginning from around 2011, the series has received media attention from technology publications due to hobbyist app releases for the platform, such as an unofficial ChatGPT client, a web browser, and a neural network. In recent years, however, the TI-84 Plus has been increasingly criticized for its antiquated technology and poor value for money, with critics claiming that its continued sale is a result of Texas Instruments' calculator monopoly.
