What famous inventions have non-famous alternatives or competitors?
Not sure if you want equivalent quality, or less advanced, but here’s a few. Note that they may not all exist in the same universe. One or two may be my own “inventions.”: DVD vs. Vinyl video disks. (Way worse technology.) Commonly available internet vs. Commonly available teletype-like device. Home-processed film for home movies instead of video tape/digital Multi-disk CD (or mini-disk) Walkman instead of iPod/MP3 players Dreamcast as the dominant video game system. Electric cars have actually been around a long time, but never caught on.
