It's much older than that. We'd call low-effort licensed games from no-name companies that were primarily designed to trick Grandma at Christmas "shovelware" as far back as the GC/PS2/XBX era, and that's just as far as I can remember seeing it in print.
Even older than that, they are the root cause of 1983 games crash on the US market, and why Nintendo's approach to a walled garden was welcomed with open arms.
