They could always use advertisement. Same as in japanese tv when you get ads after half of anime they could do the same on internet. You would get it online 24h after anime (1h for paid users) air in japan but it would contain advertisements same style as in japan or normal tv. So half ep and then internet ads given by internet sponsors (so that american,european people wouldnt watch ramen or pretzel advertisement).
They would get their money from pre-paid users and they would get money from internet ads sponsors.
But actualy I dont care cause I dont watch naruto anime and I dont like streaming shity quality.
