Bingowings said: I appreciate that in modern parlance franchise has generally come to be seen as referring a series of films, television shows etc and related material but strictly speaking it refers to authorised distribution and selling.
I agree.
Bingowings said: On the Theatrical Sound section in the second paragraph part of a sentence reads "excepting the two-decades-out-of-print".
I'd alter that to "except for the two decades out of print"(if you want to add emphasis underline it, the hyphens look strange rather than percussive).
I agree with changing excepting to except, although this is preference, but you are wrong about the hyphens. It has nothing to do with emphasis: it is accepted practice when one uses a long phrase as an adjective/modifier.
