I personally from what i have read think its between 1992 to 1995 Since the Nes became obsolete, The Atari 2600 got discontinued in 1992,The Commodore 64 got discontinued in 1994,and Windows 95 came out in 1995 Which made Ms Dos sort of Obsolete since it still needed dos to run. What are your thoughts on when 80s tech culture died.

'80s tech culture IMO lasted much longer than the '80s itself, beginning around 1978 with the early Apple IIs, VCRs starting to become affordable to those who really wanted them (not quite yet to the Average Joe), the Atari VCS/2600 becomes more widely available, answering machines hit the market, boomboxes, synthesizers start to be used more in music, and Chyron graphics start to be used on video programming. IMO it lasted as late as 1992 (I recall an old post that it was the last gasp of "Cold War era" technology, as CDs had recently passed cassette players as the most commonly listened to form of music, CD-ROM was coming out and starting to replace floppy disks, most computers around that time were multi-color, cellphones started to no longer be just a novelty, modems/early Internet (even if widespread adoption was still a few years away), Windows 3.1 becoming a serious competitor to Apple, 16-bit video game systems, TVs with menu screens, and 8mm tapes for camcorders compared to clunky VHS ones. Even though CDs were out as early as 1982-83, they weren't really seen as "90s" at the time since the '80s were still fairly new despite peaking in the '90s, although when CD players started to have multi-disc changers, that sort of ushered in the change in decades. '

90s tech lasted until around 2001 when broadband, HDTV, iPods, DVD replacing VHS, sixth generation video game systems, digital cameras replacing film, Windows XP, digital cable, and compact flip phones really began to proliferate.
