By 1972, pocket calculators became more accessible as their price fell to $100, leading to the sale of 5 million units. The following years saw rapid advancements in technology, with prices continuing to decrease significantly. By 1975, the cost had dropped to $25, contributing to a yearly doubling in sales, marking a significant shift in consumer electronics.
Fast forward to 2014, and the affordability of pocket calculators reached a new low, with Texas Instruments offering a model for just $3.62 at Walmart. This evolution highlights the dramatic changes in technology and manufacturing that made such devices accessible to the average consumer over the decades.
