In 2014, franchises are not a big part of the movie business. They are not the biggest part of the movie business. They are the movie business. Period. Twelve of the years 14 highest grossers are, or will spawn, sequels. (The sole exceptions assuming they remain exceptions, which is iffy are Big Hero 6 and Maleficent.)
Almost everything else that comes out of Hollywood is either an accident, a penance (people who run the studios do like to have a reason to go to the Oscars), a modestly budgeted bone thrown to an audience perceived as niche (black people, women, adults), an appeasement (movie stars are still important and they must occasionally be placated with something interesting to do so theyll be cooperative about doing the big stuff), or a necessity (sometimes, unfortunately, it is required that a studio take a chance on something new in order to initiate a franchise).
A successful franchise is no longer used to finance the rest of a studios lineup; a studios lineup is brands and franchises, and thats it. Disney, of all the big companies, is the closest to approaching the absolute zero of this ideal its movies are virtually all branded, whether Lucasfilm, Pixar, Marvel, or Walt Disney Studios and anyone who doesnt imagine that other studio CFOs are gazing at that model in envy and wonder is delusional. Disney is a kingdom of subkingdoms. Nothing minor or modest need apply.
