Informative Speech on Cell Phones
(Plays iPhone Ringtone) Hear that? That is a cell phone ring and it’s going off. And many of you have probably heard this before. Hello, My Name is Chenzel and today I will be telling you more and more about cell phones.
Do you remember a time when cell phones were rare? Today, it's hard to imagine a world without them. Even if you don't own one yourself (which as I can see everyone in this room own one), you probably see dozens of people talking on a cell phone every day. The rate at which we adopted the devices is astounding. But who invented them?
To get the answer to that question, we need to look back more than a century. Alexander Graham Bell invented the telephone in 1876. And then in 1900, on December 23 on the outskirts of Washington, D.C., an inventor named Reginald Fessenden accomplished a remarkable feat: He made the first wireless telephone call. He was the first to transmit the human voice via radio waves, sending a signal from one radio tower to another. Together, they led a team to invent a cell phone under the company of AT&T. The phones were expensive and some weighed up to 80 pounds (36.3 kilograms) -- not the sort of device you can carry around in your pocket! But then, a competitor made a bold and cheeky move in 1973. That competitor was Martin Cooper, who at the time was an executive with Motorola, one of AT&T's competitors. Cooper led a team that designed the first practical cell phone. It was called the Motorola DynaTAC, and it still wasn't a tiny device -- it was 9 inches (22.9 centimeters) long and weighed 2.5 pounds (1.1 kilograms) which is also called a brick.
Believe it or not, back then the only purpose of the mobile phones was to make phone calls. But Nowadays, over the past 40 years or so. Technology has gotten bigger and bigger. And “SMART” is not only a term that implies human intelligence. Smart is in. Smart is a predecessor or phone. Now, you get the smartphone. Mark Warzowski of
