How Technology Has Developed

Mobile and Telephone Development.
Over the years mobile phones have changed and developed drastically, once called 'cellular phones' the device was made to make and receive phone calls over what was called a radio link, the first telephone was made in 1870s and looked like this..

 

And our modern day house phones most people have today look something along the lines of this..

 
In the 1940s, mobile phones were invented, they were much more handy than the telephones as they were portable and could be used anywhere, over the years mobile phones have developed a large amount from the oldest brick phone to the brand new IPhone 5s that has only recently come out and is extremely popular,this time line shows the difference and change in mobile phones over the years..



In this photo you see how phones have gone from looking like bricks and being massive to gradually getting smaller, thinner and eventually touch screen, the graphics also change massively.
