The history of mobile phones as we know them started with the introduction of Motorola DynaTAC 8000X, which was the first cell phone offered commercially in 1984. It was a huge brick-like phone which measured 10 inches (not including its flexible "rubber duck" whip antenna), weighed 28 ounces and cost $3,995 ($9209 in present-day terms). Motorola paid $20m (almost $50m in today's money) to 20th Century Fox to promote DynaTAC 8000X as Gordon Gekko's phone in "Wall Street" (1987). After that the sales of DynaTAC 8000X skyrocketed and doubled Motorola's annual revenue.
