Inventions
Model of Alexander Graham Bell's Telephone - Alexander Graham BellIn the 1870s, two inventors Elisha Gray and Alexander Graham Bell  independently designed devices that could transmit speech electrically (the telephone).  Alexander Graham Bell patented his telephone first. Elisha Gray and Alexander Graham Bell entered into a famous legal battle over the invention of the telephone, which Bell won.
The telegraph  are  wire-based electrical systems, and Alexander Graham Bell's success with the telephone came as a direct result of his attempts to improve the telegraph.

Every day we see a new model and new software as far as mobile phone are concerned. Now mobile phones are competing with computer and television. And it has become a unique tool where it is substituting computer and television in a single miniature piece.

Future phones are being touted as the ultimate multifunctional gadgets and are expected to be more closely embedded in our day-to-day lives than ever before.Some experts predict that the future mobile phonese will become remote controls for our whole lives, One thing is for certain, the technology involved in mobile phones and mobile networks has developed so rapidly over the last few years that it's going to be an exciting ride.

Scot, John Logie Baird demonstrated the world's first television system to the public in 1925.This television is in the 40's. In that time remote control isn't invent yet,so people have to go the front of the television to spin the channel wheel ,imagine you have to run back and forward time to change a channel ,do you know how hard it is.

The television is getting thinner,so  we can just hang it on the wall. It is also getting lighter, so we can move it around easier and it don't need that much space. Television has good HD quality .

Maybe at the future there is hologram,you only put a tiny projector on the ground , and you don't need a screen ,and the show will like flouting in the air.
