Texas Instruments also continued to manufacture equipment for use in the seismic industry, and GSI continued to provide seismic services. After selling (and repurchasing) GSI, TI finally sold the company to Halliburton in 1988, after which sale GSI ceased to exist as a separate entity.
By the mid-1980s, industrial computers known as PLC's (programmable logic controllers) were separated from Sensors & Controls as the Industrial Systems Division, which was sold in the late 1980s to Siemens.
In 2000, Texas Instruments first implemented an e-commerce platform on TI.com as a way to sell its Code Composer Studio™ software tool directly to customers. With TI.com, purchase managers and design engineers have access to TI products that are immediately available for shipping. The platform has grown to include tens of thousands of TI analog and embedded processing products. In 2020, TI added several features, including full and custom quantity reels, multiple payment options, lines of credit, and flat-rate shipping.
TI's remaining businesses consisting of DLP products (primarily used in projectors to create high-definition images), calculators and certain custom semiconductors known as application-specific integrated circuits.
The ASICs business develops more complex integrated-circuit solutions for clients on a custom basis.
In 2007, TI released the TI-Nspire family of calculators and computer software that has similar capabilities to the calculators.
Less than 3% of Texas Instruments’ overall revenue comes from calculators, part of the $1.43 billion revenue in the "Other" section in the company's 2018 annual report. Nevertheless, the calculators are a lucrative product. For example, estimates have a $15 to $20 cost to produce TI-84 Plus which likely has a profit margin of at least 50%.
The TI community reached the height of its popularity in the early 2000s, with many new websites and programming groups being started. In fact, the aforementioned community sites were exploding with activity, with close to 100 programs being uploaded daily by users of the sites. Also, a competition existed between both sites to be the top site in the community, which helped increase interest and activity in the community.
