  3. The transistor radio was the first portable radio. It was made in 1954 by a Japanese company. It was the most popular way of listening to music in its time. Bell Laboratories demonstrated the first transistor on December 23, 1947. The scientific team at Bell Laboratories responsible for the solid-state amplifier included William Shockley, Walter Houser Brattain, and John Bardeen. After obtaining patent protection, the company held a news conference on June 30, 1948, at which a prototype transistor radio was demonstrated.

  4. The walkman was built in 1978 by Sony. The CD walkman was initially launched in 1984. It was officially called the Discman and this name has been used informally to refer to such players. The names Walkman, Pressman, Watchmen, Scoopman, Discman, and Talkman are trademarks of Sony, and have been applied to a wide range of portable entertainment devices manufactured by the company.

  5. iPod Classic is the first iPod created by Apple Inc. It was released on October 23, 2001. It had 5GB and can hold up too 1,000 songs. Now the iPod Classic is referred too as the iPod. The second generation iPod was introduced on July 17, 2002. Using the same body style as the first generation, the hold switch was redesigned, a cover was added to the FireWire port, and the mechanical wheel was replaced with a touch-sensitive wheel.

  6. The iPod Touch is a portable media player, personal digital camera, and Wi-Fi mobile plantform designed and marketed by Apple Inc. The product was launched on September 5,2007, at an event called the “beat goes on”. The iPod Touch adds the multitouch graphical user interface to the iPod line. It is the first iPod with wireless access to the iTunes store

  7. These music players are environment friendly. This affected the way people listen to music, now its not just listening to music you can get on the internet, play games , text people, and make phone calls. So they are much more than a music player. There are numerous positive effects of iPods on both indivuals and society as a whole. Not only do they fill the ears of listeners with music that makes them happy, iPods also maintain personal space, encourage self-expression, and strengthen community. Many people fear that the unintended implications of the iPod are causing irreversible damage upon society. The root of those fears center around the alleged isolating properties of iPods, the increase in iPod-related theft, and branding of users.
