An anonymous reader shares a report: Hulu this morning announced it's finally adding HBO as an optional add-on for subscribers, as well as HBO-owned Cinemax. The premium networks will be offered to those who subscribe to Hulu's on-demand service plus those who pay for Hulu's new live TV service, including both the ad-supported and commercial-free versions. As on most other streaming services, including HBO NOW, the HBO add-on will cost subscribers an extra $14.99 per month. Cinemax is a more affordable upgrade at $9.99 per month. The deal's timing comes just ahead of "Game of Thrones" big summer release, which will allow Hulu the opportunity to capture some number of subscribers for this premium upgrade. Many HBO viewers only pay for the streaming service while the flagship series is airing, as they want to watch it live but no longer pay for cable TV. Now, they'll be able to watch the show live or on-demand, along with past seasons of other popular HBO series, like the "The Sopranos," or catch up on newcomers like "Westworld," along with all the other shows, sports, comedy and music specials, and movies that HBO offers. Some of HBO's other notable originals include "Veep," "Last Week Tonight," "Vice," "Silicon Valley," "Big Little Lies," and "The Night Of." It's now home to kids classic "Sesame Street," too.
