Question

Like internet and cell phones how has that changed in the U.S. since 1945?

Answer 1

The advancement in technology amazes me.
Medical technology it's self has progressed to transplanting body parts.
We no longer have to spin a rotary dial on a telephone. With that same device and all of the advancements we can send a picture, write a letter and talk.
Every Home now has multiple TV's.
Not just 1 on a block. My grandpa had a television and always turned the lights off when the lights came on there would be neighbors and sometimes stranger's in the home watching it.
Calculators today no longer have 10 rows of numbers across and 10
columns down ,with a hand crank

I learned on the far upper right hand corner one.

We can fly to the UK in a matter of hours. On super sonic jets we can send people to outer-space and to the moon.
The list goes on and on for advancements. No longer do we have to keep piles of plastic to listen to music we have CD's.

The thing I like best is the "Computer"
I can sit here and tell you of all things that were available then and in just a few minutes you can read it.
In 1945 I was 7 years old.

Answer 2

Considering the upgrades in televisions and cars, we have never had cell phones or even wireless (cordless) telepones...we had rotary numbers! Also, whoever thought about the internet! These changes in technology help us communicate around the world in a matter of a few seconds!

Answer 3

Well, television really came into being after 1945, and has since blossomed into flat panel, LCD displays from the "tube." There are more than a handful of local stations, one can get cable, digital cable, or satellite television. They come in color.
Telephones have changed from rotary to dial, to cordless and cellular. You no longer have to call an operator to place your call (I can't remember when that ended completely), rather you just dial the number.
Computers exist-previously they would fill a huge room and perform very few functions compared to today's computers.
Typewriters are very, very scarce since most work is done on computers.
The internet was born in the postwar period. People now communicate through e-mail rather than through hand-written letters. You can do research online, rather than having to go to a library.
Cars are more advanced.
With the launch of satellites, we can look into space, communicate, and locate people and things through GPS, while monitoring things on our planet.
Weather forecasting is more advanced.
We can travel into space, thanks to NASA.
Photos and movies are taken/shot digitally, loaded onto a computer, and edited/stored without you ever having to touch a negative. You can watch a DVD or VHS at home, rather than having to go to a movie theater...and you can TiVo the TV shows you'll miss when you do go to the movies. Sound and special effects are edited and rendered digitally, and many theaters are switching to digital projection systems.
You can download your favorite songs from iTunes onto your iPod or burn them to a CD, rather than having to lug around cassettes, 8-Tracks, or records. You can listen to many radio stations locally, via satellite, or online.
