TI Graphing Calculators Hold 20-Year Monopoly on US Classrooms

U.S.-based Texas Instruments’ graphing calculators have remained a school necessity for more than 20 years. According to reporting by Verge Staff at The Verge, a new episode of the podcast Version History takes up the history of this monopoly. Joining host David Pierce are Nilay Patel and Victoria Song of the same outlet. Released on September 20, 2026, Season 5 Episode 2 examines the ties between schools and a specific product.

The same calculator has been on most kids’ back to school shopping list since the early 2000’s

The sentence above succinctly shows the theme the episode addresses. It is the fact that the same model has continued to appear on back-to-school shopping lists since the early 2000s. The calculator division’s dominance is said to have an even longer history. The episode traces how one company seized the market and never let go.

The Classroom Staple Since the 2000s

TI graphing calculators, typified by the TI-84 Plus, have become closely tied to mathematics education in the United States. The situation has continued in which many students purchase the same model at milestones of advancement and moving up grades. For parents it is an expensive outlay, and for students it has also been a symbolic possession. In the episode, the hosts look back on their own experiences of using them.

Season 5 focuses on schools as its theme. The first episode covered The Oregon Trail, the educational software experienced in computer labs. Upcoming installments are planned on One Laptop Per Child, Chromebook, LeapPad, and the overhead projector. The calculator episode is positioned within that flow. The question is why an object close to stationery was never replaced over such a long period.

Multiple distribution channels are provided for the show. In addition to dedicated audio distribution and publication on a video-sharing platform, official explainers for short-form video are also provided. Ad-free audio is available for paid subscribers. The structure can be seen as targeting both audiences who consume the history of educational technology as entertainment and those interested in institutional design.

Exam Rules and Sales Networks Behind the Monopoly

TI’s dominance cannot be explained by product performance alone. In schools, the practice of teachers building lessons around the operating procedures for a specific model has taken hold. Textbooks and supplementary materials were made to match specific key layouts and display formats. Unifying operation reduced the burden of instruction. Once established, procedures have a nature that makes them hard to change.

Permission for use in exams is also an important factor. In U.S. standardized tests and assessments, the types of calculators that may be used are defined in detail. TI products were included in the approved lists early on, boosting their adoption by schools. Whether a product is approved directly affects purchasing decisions. To avoid the risk of disqualification, parents tend to choose products in line with the specifications.

On the sales side, distribution through schools also worked. Securing store shelf space during the back-to-school sales season and outreach to educational institutions accumulated. TI’s strength as a semiconductor company is also in the background. As shown by Yuexin Semiconductor Files for IPO With Over 10 Billion Yuan in Cumulative Losses, the semiconductor business carries heavy development costs and mass-production burdens. TI can be assessed as having leveraged its existing production base and financial strength to maintain supply to the education market.

Technical Reasons Outdated Designs Persisted

Related reporting by the Washington Post points to the structure in which calculators described as outdated maintain a monopoly in classrooms. A similar awareness of the issue was shown in the episode description. In terms of processing power and display quality, current mobile devices far surpass calculators. Nevertheless, dedicated devices continue to be used in classrooms. It is a market in which newness of features is not the selection criterion.

Reasons dedicated devices remained include cheating prevention and uniformity of operation. General-purpose devices have communication and recording functions, complicating exam administration. Calculators have limited functions and are easy to supervise. Long battery life and high durability also suit school use. The low maintenance and management burden is a practical benefit for schools.

Maintaining compatibility also slowed updates. Instructional materials and operating procedures accumulated by teachers are assets. Changing models means remaking materials. Schools face tight budget constraints and struggle to secure transition costs. As a result, continued use of legacy models can be seen as having become a rational choice.

Lessons for Schools in the Generative AI Era

Related materials for the show include an article by ProMarket discussing lessons for educators in the generative AI era. The calculator monopoly is referenced as a prior case concerning control of tools. A case of tool introduction into eighth-grade math reported by the New York Times was also introduced. Introducing tools affects both learning outcomes and equity. Dependence on a specific product affects long-term costs and operations.

Similar issues are emerging around the use of generative AI. The scope of permitted tools, changes to assessment methods, and updates to teachers’ instructional procedures will be needed. The calculator case showed that initial choices can become fixed for decades. Compatibility and alignment with exam systems can become stronger determinants than whether technology is new or old.

In procuring educational technology, ensuring openness and portability is a challenge. Teaching materials and assessments dependent on a specific model increase later switching costs. Standardization of document formats and support for multiple products are required. The history of calculators can be assessed as having made visible the trade-off between convenience at introduction and long-term lock-in.

Editorial Opinion

On short-term effects. This episode is seen as raising interest in procurement standards for educational technology. Adoption of exam-compatible devices is assessed as likely to be debated in schools and boards of education. Teaching-material providers are seen as strengthening multi-model compatibility claims. In the three-to-six-month range, reevaluation of calculator policies may proceed alongside guidelines for generative AI use in exams.

On the long-term view. In the one-to-three-year range, the boundary between dedicated devices and general-purpose devices is seen as being redefined. Function-limited devices premised on exam administration and usage models with monitoring functions are assessed as likely to be tested. If open formatting of teaching materials advances, dependence on specific products is seen as easing. Debate over cost burdens and equity in schools is assessed as continuing.

Questions from the editors. There is an issue of who should decide classroom standards. The balance among testing bodies’ specifications, teachers’ instructional burdens, and parents’ cost burdens is assessed as being at issue. The question remains of what conditions would prevent repeating the same lock-in in the generative AI era. Verification of whether the tool selection process was sufficiently recorded and disclosed is also considered necessary.
