The Guardian is reporting that Sky—who recently secured exclusive broadcast rights to HBO’s original programming—is launching a new high definition channel, Sky Atlantic, to feature HBO’s programs as well as Mad Men, which they recently scooped up from the BBC. The channel will cost £19 a month as part of the Sky Variety Pack, and will launch early in 2011.

Most interestingly, Sky reports that Game of Thrones is set to begin airing in April. This likely means the show will be airing no more than a month after it premieres in the United States.
