^ that sucks for Katie BIG TIME!...but it still might be broadcasted in internationally even though it probably won't be in the US

The miniseries is still scheduled to air in Canada on March 6, and will still be broadcast internationally.
But the U.S. cancellation no doubt is a disappointment in an otherwise blockbuster era for AETN president and CEO Abbe Raven and Dubuc, both of whom championed the project. AETN, owned by a consortium comprised of Hearst, Disney-ABC Television Group and NBC Universal, enjoyed its most-watched year ever in 2010, with its six Nielsen-rated networks posting combined year-over-year viewership growth in each quarter. In addition, History is now a Top 5 cable network in all demos, fueled by hit original series such as Pawn Stars and Ice Road Truckers.
The Kennedys cancellation somewhat mirrors the fate of The Reagans, a miniseries that was to air on CBS in 2003 but was scrapped when advertisers threatened to boycott after conservatives raised concerns about depictions of former president Ronald Reagan being insensitive to AIDS victims. The Reagans later aired on Showtime.
THR has learned that producers of The Kennedys might make a similar move to bring the miniseries to a pay cable channel.
