8. Digital Audio Tapes

Date: 1987

Sony's signal recording and digital-encoding format was billed as the "cassette tape killer" when it was introduced back in the mid 80s. While it offered higher quality audio output, the DAT had many frailties. Not only was the recording process more complex than cassettes, it was known for occasionally breaking down. And, like most of Sony’s gadgets, it was overpriced. Sony also encountered copyright issues as the RIAA lobbied to prevent the sales of DAT players causing other electronics companies to delay production on the players and cassettes. After CDs and minidiscs came onto the scene, it was a wrap for digital audio tapes.
