I found a good list of the Marvel timeline numbers for just the TV and movie tie-ins here:
Interesting that they don't count the '90s syndicated Marvel Fantastic Four, Iron Man
, and Hulk
shows in the same reality as the FOX Spider-Man
shows, even though a few characters and actors crossed over between them (Robert Hays as Iron Man and James Avery as War Machine guested on Spider-Man
, and at least one actor from the syndicated FF reprised their role on SpM's "Secret Wars," though the rest of the FF and Doom were recast). It was always a little ambiguous whether those two sets of shows were in the same universe or not; I can't think of any blatant contradictions. (However, those three syndicated shows don't entirely fit together with each other; the Hulk episode in IM depicts a version of Hulk's origin that's completely incompatible with the later Hulk show, although the Hulk episode of FF from the same year had a sequel of sorts in the Hulk show. But I'm pretty sure there were crossovers between the paired IM & FF shows that linked them in a shared universe.)
Anyway, this is off-topic. I guess the point is, there are other franchises where different interpretations are fully embraced as separate realities, so there's certainly room for applying that point of view to Trek tie-ins. Personally I only count some books and comics as alternate timelines -- things that could plausibly be divergent histories of the same basic universe with the same overall history and physics and evolution and geography and so forth. (I have two main alternate timelines that I put those books and comics into, one for the 23rd century and a smaller one for the 24th century, because the first one would've diverged too far by the TNG era for the others to fit in.) The rest, I just count as different fictional continuities. But other fans can and do see things differently. There's a variety of options.
