For calculating price changes over time, there will always be the question: "is this the same product as earlier?"

Without a reasonableness factor, prices can't be compared for anything. An egg from a chicken in 1940 is different from one in 2026. If we want to be pedantic, every egg is different.

But I think it's pretty uncontroversial that the prices of TVs, cell phones, and most appliances, with similar features, have fallen considerably over the last few decades.
