Dictaphone in 1947 introduced the Time Master dictation machine. This is the first Dictaphone device to use the new plastic belt instead of a wax cylinder. These "Dictabelt" machines still used a phonographic recording process, and they were not re-usable. Edison countered with the Voicewriter, which used a vinyl disk. Meanwhile, the Soundscriber and the Gray Audograph captured a sizable chunk of the market, much of it at Edison's expense. Meanwhile, important new technologies appeared, particularly magnetic tape and wire recording. The Peirce wire recorder was one of the first wire recorder dictation machines to appear after 1945.
