When The Finder was spun off from Bones did the two series ever get a franchise title or is the franchise title Bones because The Finder only had thirteen episodes?
...but then a "franchise" essentially requires that the two series have some commonality be it the same organisation (e.g. NCIS) or the same basic premise (e.g. CSI).
In this case the two series did not share this commonality but they do share the same TV universe.
By way of further example, NCIS is a spin-off of the highly successful series JAG but we don't refer to the combined JAG/NCIS franchise....they share a universe (and continue to do so) but they are not a single "franchise".
