From today 15-20, we used a lot of essential things in our way of life, many of which have already been extinct and many are on the way to extinction.
Yes, there are some things that are the subject of today's discussion on the extinction of technology and the Internet today due to extinction.
Now we have seen one of those things because of the fierce state of technology and the growing power of the Internet.
1) Public Phone:
We all know that in 1876 Alexander Grahambell invented the telephone. But if you do not know the first public phone was established in 1878. In 1878, in the presence of a helper, public phones were set up in the hotel lobby, railway station, any populated market. After finishing the first customer call, the money was given to the assistants. But it was not possible to call a phone this way, and it was annoying. Coin-operated public phones were established from this point of view in 1889. First posting and then a free pay public phone was launched in 1898, which was named No. 5 Coin collector. The first street public phone was established in 1905. Launched in 1950, the 3-slot dial public phone, which had the advantage of making phone caller 10 paisa coins, nickel metal coins and coins made of coins. Slowly it became popular and millions of public phones spread around the world. The picture below is not familiar with the public phone,
But so popular public phones today are almost extinct almost. One of the reasons for this is the arrival and expansion of the Internet. As a result of the expansion of the internet, email, social media, voice chat applications, after that the mobile phone has been contacted by the clock. If we have a cell phone, why would we talk to the public on the street. On the way to the extinction of public phone due to the latest invention of technology and technology.
But public phone makers are willing to wait until the end user. So maybe we will see a little more but this public phone.
2) Cassette and CD:
The cassette was the only one to hear our songs long ago. See here today there is no cassette. CDs, DVDs have taken place in the cassette. Many of these popular CDs and DVDs can not hold their position. Due to the latest invention of technology, they are still on the verge of extinction.
Now we look back a little bit. In 1958, RCA Victor discovered the first stereo cassette, whose size was 5 "x7" and it was pre-recorded so it was in vain. In 1962, Dutch-based company Phillips invented and marketed the first compact audio cassette. It was created by a quality 1/8 inch polyester tape. The record and playback speed was 1.7 / 8 inches per second. When the cassette gained fullness, it could playback at 30/45 minutes on both sides.
Then Philips and Sony joint efforts began in the mid-1970s. In 1982, the CD came in the joint effort of these two companies. After that we saw the popularity of the CDs. The cassette was lost. Capture the CD market. This CD is almost extinct today. The capacity of the CD is 700 MIB and the time is about 80 minutes.
This time there is little to see why they are extinct. After the discovery of CDs and DVDs lost in the popular cassette space of the times. And now we listen to music online for the promotion of technology and the Internet, we see the movie. Listen to music on mobile, why buy cd? And the latest connection to the technology is FM radio. World Now FM Radio triumph. One music station is now in the pocket of the people. For this reason, CDs, cassettes are on the way to extinction.
3) Rolodex:
Rolling and Index Matching Rolodex is a combination of two English words. This is a machine to store any data on which the information was placed on the paper or card and placed on this machine. See the Rolodex image-
A Rhodex used in the 1970s
Arnold Neustadter and Hildaur Neilsen discovered it in 1956 and first marketed it in 1958. At that time there was no virtual social network, no address book, smart phone, not online storage. But still people had business and personal information, the need to enter the address, the public phone number should be kept in mind and many more such information should be remembered. And this information was written by people on paper and in the rollodex.
This device is extinct today due to technology and internet. Today we have many measures to store information including mobile phones, smart phones, notebooks, tabs, card holders, online storage. These are the history of this device called Rolodex.
