  • 2. IT’S ALL GONE… • Innovation is continuously taking place with improvements or additions to gadgets. • In the last ten years, several common gadgets used have gone out of circulation. • Many commonplace utility gadgets (using electricity as their energy resource) have been dying off faster than one would have imagined. • Here are some gadgets that disappeared :
  • 3. FLOPPY DISK • Old computer CPUs had a slot where these drives could be inserted. • They were usually used to store text or small pictures. • Floppies had viruses that infected the PC. • Added to that was their small storage capacity of 1.44 MB. Nowadays, a single picture can easily take up 1.50 MB. • They have been replaced by :
  • 4. CDS, DVDS AND PENDRIVES • Floppies were replaced by CDs, DVDs and Pen Drives which offered higher storage capacity and were easy to carry. • They enable high data transfer speeds and are generally virus free. • Due to the emerging cloud storage, these devices also face extinction.
  • 5. PAGER • A pager was a wireless telecommunication device that had a small display and had a number to which a person can send small messages. • Popular in 1990s, it was the first portable communication device. • It was used usually to send messages like “call me”, “reached home”, etc. • They paved way to :
  • 6. MOBILE PHONES • They took the place of pager when they became affordable. • Mobiles offer fast communication. • Keypad mobiles are losing their significance to the new touch smartphones which are capable of delivering high speed, graphics, storage and multitasking.

  • 9. GRAMOPHONE PLATE • We usually catch site of these big music players in museums. There was a stick-like lever that one kept over the disk so that the tiny needle at the end of that lever made contact with the invisible grooves on the disk. • Sometimes the needle got struck leading to looping of the song. • They lost their existence to :
  • 10. MUSIC PLAYERS • Music Players are of varying sizes according to the user’s need. They have replaced the Gramophones. • They provide the finest quality of sound and do not have any looping problems.
  • 11. TV ANTENNAS • These interconnected iron bars sticking out of the roof were considered to be a symbol of social superiority. • Positioning of the antenna was a sophisticated task itself. There was one guy on the rooftop and another monitoring the signal, taking a very long time to attain the correct position. • They were soon replaced by :
  • 12. DISH (DIGITAL DTH SERVICES) • They took the place of the very sophisticated antennas. They need positioning once and are capable of providing Full HD picture. • At a time when a owning a TV was difficult, owning antennas was considered socially superior. Now, when almost each household has a TV, owning a dish is a necessity.
  • 13. FASCINATING TECH Gadgets have always enthralled the young — and young men in particular.
