2. Telephone

The telephone was invented in the 1870s and it quickly caught on as a popular method of communication.

For the first time is allowed people to talk to one another across a distance.

As with most technology, only the rich could afford to have a telephone in their own home. Most people made do with a telephone box.

But slowly, it became normal to have one in your house.

The next big change was to have cordless phones which allowed you to roam around the house with the handset.

Then the idea of a 'mobile' phone came about in the 80's. They were hardly mobile, more like had held bricks. But very soon, mobiles appeared everywhere.

Now telephones are changing again, with the appearance of Internet based services such as VoiP.
