Now a days we enjoy a lot of commodities that the technology offer us, but we have stopped to remember how it has changed.
We turned around and look at the past thirty years, only thirty, and see how pronounced the differences are.
Telephones
Today we can surf on Internet, take photos and videos , send messages, listen music and, of course,talk with other person; but thirty years ago we could do one thing with the telephone.
The disc telephones were the kings 30 years ago, but now you can’t use one of this kind of telephones unless you can get a pulse-tone converter, and you can receive calls and talk with it.
TV
Thirty year ago, watch the TV was like a familiar ritual, and it was magic, you could go with your neighbor, if you didn’t have a TV.
Today we can enjoy to more than 100 chanels, and finish to turn off the TV, because we didn’t find anything to watch.
The analogical transmition is almost disappear in countries like Spain or US, but in 1970 the majorities of the televisions were with and black.
Personal Computer
It is one of the most changed markets in the actuality, today we can do almost everything in the computer, we can talk, chat, send e-mail, study, watch movies and tv series, work, play and a lot of things more; but thirty year ago if you wanted to buy a computer you couldn’t get, you needed to build it.
