Count me among those guilty of occasionally dismissing HBO after taking a close look at the outrageous gains Netflix (NFLX 2.51%) is enjoying. You know what? I shouldn't be so quick to scoff.

The latest preview for season 4 of Game of Thrones -- a 14-minutes epic I've embedded below for your viewing pleasure -- suggests the network has invested heavily to give GoT viewers everything they want from the show: a bloody, tragic, terrifying epic tale featuring lovable (Sam, Dany), loathsome (Joffrey, Tywin), and terribly complex (Jaime, Tyrion) characters.

It's an impressive formula created by author George R.R. Martin. His A Song of Ice and Fire books inspired the show. Season 4 opens on April 2 and will apparently focus on the second half of A Storm of Swords, volume three of the seven-part series.

History says audiences will be thrilled with what showrunner David Benioff and his team bring to screen, which bodes well for HBO parent Time Warner (TWX). Here's a closer look at recent financial trends and how they map to last year's huge jump in GoT viewership:

Good numbers, right? Sure, but the better news -- especially if you own Time Warner stock -- is that these figures represent a small part of the story. HBO has often said that GoT draws more than 13 million viewers per episode once you count those who tune in later via DVR, on-demand, repeats, and the like. Within spitting distance of the zombie megahit The Walking Dead, in other words.

Will 2014 bring further growth? It sure looks like it. The preview below has already amassed nearly 3.9 million YouTube views in 24 hours. A season 4 trailer released a month ago has more than 17 million views. Season 3's previews never made it past 3.8 million views.

Winter is coming alright. And unlike the poor souls stuck in Westeros, Time Warner investors should benefit from the chill.
