Do the ratings for the Vikings TV show matter to the folks over at History? The series saw another big drop in the ratings last year — down 28% in the demo and 44% in viewers — but the cable channel renewed it for a supersized fourth season anyway. Will the numbers keep falling? Cancelled or renewed for a fifth season? Stay tuned.

Vikings takes place in the brutal and mysterious world of Ragnar Lothbrok (Travis Fimmel), a Viking warrior and farmer who yearns to explore (and raid) the distant shores across the ocean. The rest of the large cast includes Katheryn Winnick, Clive Standen, Gustaf Skarsgård, Alyssa Sutherland, Linus Roache, Alexander Ludwig, Ben Robson, Moe Dunford, Lothaire Bluteau, Jasper Paakkonen, Kevin Durand, Jennie Jacques, Peter Franzen, Morgane Polanski, Amy Bailey, Dianne Doan, and John Kavanagh.
