Shovelware, like 'abandonware', is a term that mutated into something else entirely, like "non-shooting games i don't like according to zombie-game-loving youtubers". You'll see this term applied to games like Tex Murphy, 11th Hour, Descent, et al.. and if they're 320x200 only, expect an unrealistic fauxstalgic comparison to Pong. It's definitely a SeinfeldIsUnfunny kind of thing, because the very existence of such games existing in the same market as their shooters offends the so-called 'pc master race'
Unfortunately many of the 90s' Windows shovelware cover the same pre-1995 Visualbasic-riddled repositories just to gain up on marketing that 500 or 1000+ number with a huge sturgeon's law ratio, so a lot of decent freeware/shareware games of the mid-to-late '90s are lost in time. The same applies to DOS as well. Gaming magazine CDs often leave that out too to make room for commercial demos, though there ARE a few that do cover them slightly, like ComputerGamesStrategyPlus...which is hardly preserved.
(by the way, 3 of the overly angled/gleamed cds in the second picture are Animation Festival (shovelware of FLI/FLC files and some '92'93 PC demoscene yay), a "classic pc oldies" Karaoke CD and some SECOND world atlas thing.
