The document summarizes key developments in the pre-history of computer-assisted language learning (CALL). It describes inventions like the Difference Engine (1833), which could compute polynomials and approximations of logarithmic and trigonometric functions. The Analytic Engine (1835) was an early general-purpose computer designed by Charles Babbage. Other developments included the typewriter (1873), telephone (1876), phonograph (1877), and technologies that helped bring photography and film to wider audiences. Figures like Herman Hollerith developed early tabulating machines in the late 1800s that helped process census data, leading to the founding of IBM. The BBC began television broadcasts in 1932 and early educational programs aired in the US.
