i look at;

1-can they pay?

credit cards and debit cards are nice aside from online sales. it's a really bad thing check cashing places are ubiquitous in your target demographic's neighborhood. even some of those with money to buy your product have no ss#'s, permanent addresses, or bank accounts.

2-can you get them your product?

bandwidth is a problem, both for tv and internet. cable's not huge in this market because of cost and getting it set up. plug some rabbit ears into your tv and you'll see a lot of spanish channels. internet-cost and setup at a semi-permanent addy with ss/credit checks factor in here as well.

3-will they pay for it once you give it to them?
corruption feels as comfortable as a favorite blanket to most in the global south and these people are used to living with two economies existing openly at the opposite ends of their legal spectrum.
central and south americans are pretty efficient at creating black markets and quite comfortable using them. if you can copy it, they'll be selling it to each other.

4-do they all really want it in the first place?
-hardcore catholicism. assume you're looking at one person who habitually crosses themselves while muttering in rushed-spanish for every one of those topless girls on the beach. a lot of the porn shot in these countries is by gringos selling it in their own countries and central and south america are poor. poor people will fuck on film for you and poor places with tourism mean lots of hookers are around, that doesn't mean society as a whole embraces porn as much as jesus icons and crosses.
