WASHINGTON - A huge change in technology was made on this day in 1973.
Martin Cooper, a Motorola executive and researcher, made the first analog mobile phone call. But his phone was quite a bit different from those that people use today.
It weighed 2.5 pounds and looked a like a brick. It also took 10 hours to charge, which provided for 30 minutes of talk time.
