Almost anything recreational and subscription-based seems to fit -- Netflix, for example -- unless we're arguing that this sort of thing isn't really a SaaS and different economics apply. Even if content-centric services are excluded, presumably all the recreational apps with some sort of tracking component would still qualify.

I agree, if you have a consumer product and are trying to get a place in the customer’s monthly budget for entertainment/recreation, a different set of rules probably apply. These cases probably aren’t as central to what is thought of as “SaaS.”
