The cliffhanger at the end is presumably referring to modern karaoke machines: >In 1992, a scientist named Yuichi Yasutomo created a networked karaoke system for Brother Industries. Called "tsushin karaoke" ("communications karaoke") it served up songs in MIDI format via phone lines to modem-equipped karaoke machines. This new technology swept Japan; by 1998, 94% of karaoke was being sung on networked karaoke machine…
I get what you’re saying but Brother is a very large company with a variety of successes, and hitting on 100 years of existing. It is OK to do things, sell them for a while, then to no longer do things. There’s still merit there!
The world turns not on the massive scale of B2C products, but on the myriad of weird bespoke products that are sold to a handful of businesses, whose existence a small fraction of the population even realize, and who sputter out of existence afterwards. Yet those projects still represent something valuable to people for a window of time important enough to matter.
