In actual release terms the top franchises(to me) that are known for this are:
1.)New Super Mario Bros.
2.)Call of Duty(Ridiculous milk y'all)
3.)Final Fantasy (Of late, mainly the stupid XIII saga)
Basically you're making a game because you can do it quick, cheap(Variant upon games), and you know tons of people will buy it no matter how stale it gets. Never drink rotten milk btw.
