In the 1980s cellphones were reminiscent of bricks!


(Above is a prime example of a cellphone from the '80s)

The first cellphone that was widely used was the Motorola DynaTAC - a bulky phone that could barely fit in your pocket, hardly effective - but it was a product of its time and was used by American's and the English alike.

Phones have altered not only in looks but in functions: in the 1980s people couldn't even comprehend the prospect of playing games on your phones, now phones are like personal computers. It's insane really to think about how many durastic changes there has been in technology going back to the 1980s.

Phones were initially used for phonecalls - now phonecalls seem to be a rarity among teenage cellphone users.
