Cell phones or Mobile Phones: When cellular phones were introduced to the public in 1983 by Motorola called the Motorola DynaTAC 8000X, all the phone could do is just call other phones. After that was released, cellphones became a huge public demand and they made car phones which were a phone that was on the wall of your car. Then in the 1990's they created 2G, which stood for second generation of mobile technology. This decreased the chance of calls being dropped and also improved the sound quality. Later on in history, they went from just mobile calling to SMS texting, 4G internet, built-in-cameras, BlueTooth (which lets you send data over a radio transmissions), Face Time calling, live television, and so much more.

Internet: It was created out of a Defense Department experiment for wartime communication in 1969, and after a long time (the 1990's) the Internet was became useful world-wide. But it was very slow and lagging a lot, but after years of work on it it became a lot faster and better with high speed. And now it's on mobile phones such as the iPhone, and almost every phone now.

Pagers: Pagers are a personal radio communication thing that sends a radio message just to the person with the pager. The first pager was Motorola's Pageboy I. Introduced in 1974, it did not have a display screen and it couldn't store messages as today's phone can.

They became super popular and were almost used by everyone in the 1990's. By 1994, there were over 61 million pagers in use. Later on, pagers died out because of cellphones and other evolving technology.

Radio: A radio is a box that converts signals of electromagnetic waves. The first ever successful transition was in 1896 by a man named Guglielmo Marconi; it traveled about a mile.

Television: Paul Nipkow made a box that shows pictured images onto a screen that has the colors red, blue, and green making the images that you see. They were very close together. But the first ones were just about 3 inch's around and in black and white with very low quality.

Thanks to that invention, millions of people were able to see some of these historic events. On Aug. 28, 1963, Martin Luther King Jr. gave the iconic I Have a Dream speech. In 1965, NBC broadcasting 96 percent of their shows in color, which was a lot for that time. Then, MTV debuted on 1980, completely changing the music and television world with something called music videos. The very first thing that they showed was the aptly named Video Killed the Radio Star by the Buggles.

Now, in 2011, you can have a 3D television and have the HD disc player, Blue Ray. Soon holograms will probably be next big thing.

Satellite: The first satellite was made and launched by the U.S.S.R on October 4, 1957, its name was Sputnik 1. Later on they launched another one on November 3, Sputnik II. It carried Laika, a dog, which was the first living thing to go into space.

Now satellites are in space for many uses, as radio, television, GPS, military services, and many more uses, all thanks to Russia and all the other countries that had something to do with it.
