We can only hope.
In general, tie-in book lines tend to fade away after the original shows vanish, but there are several notable exceptions. Star Trek,
of course, but also Doctor Who, Monk,
and Murder She Wrote.
I believe the Diagnosis: Murder
books had a healthy afterlife as well.
And there were Dark Shadows, Columbo,
and Rockford Files
novels published long after the TV shows had gone off to TV Valhalla.
Heck, I picked up a new Kolchak:The Night Stalker
novel at Barnes & Noble earlier this week--with Darren McGavin on the cover!
