Voicemail

During the late 1970s, Gordon Matthews develops the technology that will eventually be called voicemail. His Voice Message Exchange manages electronic messages in a digital format. Matthews forms the Voice Message Express (VMX) company in 1979. Gordon's wife records the first greeting on the new voicemail system. Matthews is awarded a patent in 1982 and sells the first system to 3M.

MP3

Tomislav Uzelac of Advanced Multimedia Products deploys the first MP3 player in 1997. Five years earlier, the prestigious Fraunhofer Institute Integrierte Schaltungen research center in Erlangen, Germany laid the foundation for MP3 by researching high quality, low bit-rate audio coding through its project named EUREKA. By the end of the 1990s, the MP3 technology become a huge commercial success.

DEC

MIT colleagues Ken Olsen and Harlan Anderson establish Digital Equipment Corporation (DEC) in 1957. They began building small digital hardware modules that can be combined together to be used in a lab setting. By 1961, the company is making a profit and begins construction of their first computer, the PDP-1.
