ELI5: How the hell do the companies making all those free (and generally shitty) apps afford prime time television commercial slots?

Actually, Tribal Wars 2 was pretty cool for a few days, but that Battleship one got boring as fuck quick.

Freemium games. They are free to download, and essentially are built to frustrate the user, unless they are willing to pay money. Candy crush is an example, you get X amount of attempts every 24 hours to finish a level. If you fail, you either way, or pay 2 bucks and get to go again.

Now spread that to 10 million people, because fuck it, its free. Not all of them will pay the 2 bucks, but those who do, might also pay more than once, and fairly regularly. Now you have a shit ton of money.
