The PC isn't what I had in mind as comparison; it did not become a meaningful gaming/non-business software platform until cheap clones c. 1985 gave it a substantial home presence. I chose December 1983 because it was close to the peak of the Tandy 8-bit market. Compare the TRS-80 magazines I mentioned to Compute!'s Gazette's December 1983 issue <https://archive.org/details/1983-12-computegazette/mode/2up?view=theater https://archive.org/details/1983-12-computegazette/mode/2up?...>. It's still early in the C64's lifespan, but Atarisoft, Epyx, Sierra, SubLOGIC, Avalon Hill, Infocom, and Access already have a presence. A year later <https://archive.org/details/1983-12-computegazette/mode/2up?view=theater https://archive.org/details/1983-12-computegazette/mode/2up?...>, by which time the C64 has essentially seized the entire US 8-bit non-Apple market, Broderbund, EA, Sega, Weekly Reader, Davidson, SSI, and MicroProse are also present.
