There’s going to be a big nationwide free preview of Showtime from Friday January 6th through Sunday January 8th to promote the series premiers of House of Lies, Shameless, and Californication. They’ll also be showing the premier of The King’s Speech.
So far I can confirm that this is going to be available on DirecTV, Charter, Comcast, Cox, Verizon FIOS, Mediacom, and RCN. No word yet if Dish Network will be showing it.
