Circa 1983 Motorola introduced their grey, “Brick,” cellular telephone taking mobile communications out of the bag and into our hands. It was big, clunky and it ONLY made phone calls. It was expensive to buy and even more expensive to operate. Initially it was a very exclusive crowd that carried technology like this.
Then as time went on the technology developed. The phones got smaller and cheaper to use. The functionality improved and the batteries lasted longer. More and more people adopted the idea that having mobile technology was beneficial to their lives, and new demand was created.
