• 1969: LANPAR (LANguage for Programming Arrays at Random) emerges as a significant technical advance. Notably, LANPAR allows users to write equations using natural-language formulas rather than arcane code, and introduces forward referencing (the ability to reference cells or data that have not yet been defined), which becomes a critical feature in all subsequent spreadsheet designs. These concepts pave the way for the interactive, user-friendly spreadsheets known today.

• 1978–1979: The introduction of VisiCalc for the Apple II marks a seismic shift in the computing landscape. As the very first commercial spreadsheet application, VisiCalc transforms computers from hobbyist curiosities into practical business tools. Its grid structure, filling and copying of formulas, and recalculation of dependent data become must-have features, inspiring other software. VisiCalc's popularity establishes the spreadsheet as an indispensable productivity application, leading to rapid adoption of personal computers in enterprises and the official birth of the spreadsheet software industry.
