Fox News compiled a list of "dying" technologies, which is called "Gadget Graveyard: 10 Technologies About to Go Extinct". Technologies popular in XX Century destined to become obsolete very soon are: landline phones, floppy-discs, wristwatches, VCRs and VHS tapes, beepers, film cameras, typewriters, the Walkman, Discman, and MiniDisc Player, Dial-up Internet access, and DVDs.

It may not be a dying technology, but the CES conventions that drew 300,000 people are long gone, too. This year we had 112,000 attendees, last year about 98,000.

The economy is a huge part of it, but so is the pace at which new technologies come out.
