Evolution of portable audio
- 3. In the year 1954, I.D.E.A (Industrial Development Engineering Associates) introduced the first portable transistor radio, The Regency TR-1.
- 4. The TR-1 had a simple design yet was very expensive. Its price was $49.95, which would translate to around $325 in todays standards.
- 5. Its battery life was also very short, taking 22.5 volt batteries, which were also quite expensive.
- 6. Next came the Norelco Carry-Corder 150, the first portable cassette player. This device weighed 3 pounds and could play 8-track tapes as well as cassettes.
- 7. After the Carry-Corder came Sony Walkman TPS-L2.
- 8. Consumers were amazed by its size as it was only a bit bigger than the cassette it played, as it was pocket sized and came with light weight headphones, which were new at the time.
- 9. The Walkman continued to be the most popular until CDs started to catch the publics eyes. Sony saw this and decided to reinvent their product. Thus the Sony Discman D-50 was born.
- 10. 1948, the Discman D-50 was created and again was an immediate hit among buyers. This was the first Compact Disc player, also a bit larger then the CD it played.
- 11. Last but not least came Apples iPod, which wasnt that different from other mp3s, except for its sleek design and simple wheel.
