1. Changes in music technology By Sophie

2. Record players The record player was invented by a man called Thomas Edison. It was invented in 1877. The record player is also known as a ‘Phonograph’. Thomas Edison was more interested in the science bits of the record player than the music bits, so advances on the original design were left to others. The record player went through many changes throughout its history. Thomas Edison's record player played using tin foil wrapped around a cylinder with sounds recorded on dents in the tin foil. Record players that had wax-covered cylinders came in the 1880’s, and the first record player to use a disc (initially made of zinc) arrived in 1887.

3. Gramophones The first listening device (which was called the gramophone) was invented by a man called Emile Berliner. The gramophone was invented in 1887. Emile Berliner was the first inventor to stop recording on cylinders and start recording on records. The first records were made of glass, later zinc, and eventually plastic.

4. Music tapes The Music tape was invented by the company ‘Philips’. The music tape was invented in 1963. The music tape was originally for recording your voice, but in 1966, the Mercury Record Company thought people would like it more if it could play music. The music tape was very popular because it was a lot smaller compared to the gramophones and record players. It was also very popular because it was portable.

5. Compact disk (CD) The CD was invented by James Russell. The CD was invented in 1965. If you could stretch out into a straight line all the data (information) stored on a CD, it would reach for over 6.5 km in length. CDs are made mostly of a plastic called polycarbonate plastic. The CD is read by a laser which allows it to be read with only the laser beam touching the information (the sound). It was originally designed to hold 60 minutes of music, but then they were later redesigned to hold 74 minutes in order to hold the entire "9th Symphony" by Beethoven.

6. IPod The IPod was invented by a man called Steve Jobs. The IPod was invented in 2001. Over 40% of the money Apple makes comes from selling the iPod. By 2006, 41 million iPods had been sold. An IPod can hold as many as 40,000 songs. The IPod does not sand for anything, it was chosen by a man called Vinnie Chieco. He got the inspiration from the movie ‘2001’.

7. Listening devises timeline 1887 Gramophone 1877 Record player 1963 Music tape 1965 Compact disk (CD) 2001 IPod Overall... The technology in listening devises has changed in many ways, from being big and chunky, to being small, portable, and faster.
