Other than live TV, I refuse to pay for any service that gives me ads. The trailer for another show on the same service before the movie/episode starts (like on Prime, HBO Now, etc.) are fine. And I can live with ad-free Hulu and CBS All Access at their current prices, especially since they give me a free month or two every year. Netflix is already $13 for their basic HD-quality level. I can't see myself paying anything more in the near future to get an ad-free version of their service. Some of their originals are really good, but not that good; and by the end of the year, that's all they will have to offer beyond older movies and the few network cable TV shows they haven't lost the licenses to yet.
