NEW YORK (AP) — A cell phone was first used exactly 40 years ago.

On April 3, 1973, the first handheld portable phone was demonstrated
for reporters by Motorola executive Martin Cooper (pictured) on a New
York City street corner.

Cooper contacted Joel S. Engel, of Bell Labs, using a Motorola device
that looked like "a small, domesticated version of military walkie-talkies,"
according to an Associated Press report at the time.

The device weighed just under three pounds. The iPhone 5 weighs just
under 4 ounces.

Jacob Schick introduced the first successful electric shaver to go on the market
from his factory in Stamford, Connecticut. They first sold in New Your City for $25
each (equivalent to $350 today). Schick sold about 3,000 shavers the first year,
and sales increased until 1.5 million were in customers hands by 1937.

Despite some early claims, they didn’t shave closer than a wet steel blade, but
they were convenient to use.
