From the earlier history of the Internet

 

                2 technologies from the earlier history of the Internet (before the Web, or pre-1991 period) 

                    - one which has become obsolete and been replaced by more modern things, and 

                    - another which survives to this day. 

                                                                                    The CD

Who uses CD's anymore? And for that matter, VHS and cassette tapes. Thanks to the MP3 and MP4 we don't even need things that go in disc drives to watch TV shows or movies. In fact who even needs a disc drive?

The 1990s are characterised by the dominance of the compact disc and the resulting spike in income in the music industry.  The 12 cm CD transformed the industry and the way consumers experienced music, representing a fundamental shift from analogue to digital technology.While the CD began to lose importance at the beginning of the 21st century, it inadvertently established a digital culture, one that is now embedded in society through streaming and downloads. The 1990s represents a time in history when digital technology and the Internet's ability to support file sharing revolutionised the music industry. 

                 The Fax

    Having experienced a boom in the sixties, the fax rapidly developed among private individuals, and especially in companies, many of which still use it. For legal or HR departments, and for health, real estate or finance professionals, the fax remains the best means of communication to combine efficiency and legal enforceability. It is therefore the preferred channel for sending important documents in complete security and reliability.

    Although email is fast, it is still strictly forbidden to use it to send personal data or official documents in many countries. While this practice is legal via the fax channel.

Admittedly, sales have fallen heavily but "the market is far from having disappeared". In Japan, the fax is still widely used. In Europe too, but to a lesser extent.

It was said to be condemned to gather dust in attics and museums. Twenty years after the arrival of the Internet, however, the fax has not yet retired, even if its horizon has narrowed.
