The light bulb then used a lot more electricity and did not last as long as the energy efficient light bulbs are today.
Todays energy efficient light bulbs can last between 3-25 times longer. The light bulbs today are much more energy efficient because they use between 25 and 80 percent less energy. They are much less expensive too. |

Edison's kinetescope was much bigger and harder to move around than ones today. They enabled only one viewer to view the moving pictures at a time while movie projectors today enable hundreds of people to watch movies at a time.
The movies back then were actually just pictures moving and were black and white while today they are color and 3-D. |

Recording devices today are so small that they can fit in your pocket but back then they were huge. You can also play back your talking instantly and fast forward or back track.
For the phonograph you had to speak loudly or sometimes even shout. The recorders today pick up almost all speaking noise. They are still used for the same reasons like recording music, records, and audio readings. |

The telegraph was the nineteenth century's version of long range text based messages. Back then companies like Western Union Telegraph Company would have to hire and train experts just to be able to use the telegraph machines (of course they became easier to use once Edison improved them).
Now there are phones that text, call, surf the internet, and other things that are much more advanced than the telegraph. Anyone can use them , young or old, not trained professionals! |

A decade after the 1900s, Thomas Edison developed the alkaline battery pack. Its main use was for automobiles. The main problem with them was that it was difficult to replace the chemicals needed to power it. It also did not last as long as today's battery.
Today's battery lasts much longer. Like Thomas Edison's battery, today's battery is very popular. The batteries today, like Duracell, are used for many things. Without it ,we would not be able to power any electrical mechanisms. Every day life would not be the same without batteries. |
