Streaming giant Netflix announced it had hit an important number the other day. As Andrew Wallenstein of Variety reports:

Netflix reported 29.17 million domestic subscribers in the first quarter of 2013, surpassing HBO for the first time.

Netflix, which ended 2012 with 27.15 million domestic subs, added just over 2 million subs, according to first quarter results issued Monday.

HBO ended 2012 with 28.7 million subscribers, according to data from SNL Kagan.

With HBO’s popular Game of Thrones series the most pirated show of all time, seems like a stand-alone streaming service like Netflix provides is a matter of when, not if.
