Starting today, you can watch HBO without subscribing to a traditional cable package.

Customers can sign up for HBO Now, the cable network's standalone streaming service, directly through their Apple TV, iTunes account, or Cablevision's Optimum Online for a monthly subscription of $14.99. Customers who sign up during the month of April will also enjoy a free 30-day introductory period.

If you've ever used HBO Go, HBO Now is essentially the same service, but without the aforementioned cable package. HBO Now subscribers will have access to more than 2,000 titles, including popular films, original HBO documentaries, and the network's full catalog of TV series, including Deadwood, Sex and the City, The Sopranos and more. The service also includes every episode of every season of current series like Game of Thrones and Veep.

New customers can start their free trial by visiting HBO Now in a web browser; downloading the app on an iPhone, iPad or iPod touch; or accessing the service directly through Apple TV using your iTunes account.

Optimum Online customers can purchase an HBO Now subscription online at Optimum.net/HBONOW or by calling 866-262-9329.

If you're not an Apple customer or you don't have Cablevision/Optimum Online, have no fear! HBO is working with other companies to expand its HBO Now service.

In the meantime, if you hurry to sign up, you can probably watch every season of Game of Thrones in time for the show's Season 5 premiere on Sunday, April 12 at 9/8c.
