If you signed up for the service before March 6, you’ll automatically get a free month of HBO on DirecTV Now. You’re eligible whether you never paid for HBO before or are already paying for it. The Payment History section on your DirecTV Now account will just have a little note to say HBO costs $0 every month for twelve months.
HBO is where you can watch programming like Game of Thrones, Curb Your Enthusiasm, Big Little Lies, and plenty of movies. It’s the nation’s largest premium cable channel with 71 million subscribers.
The free year of HBO on DirecTV Now expires on March 7, 2018.
