exactly it has been cancelled, speculation is that Ubisoft is
responding to declining interest in the show, which is now in the third
series. Though the show proved phenomenally popular in the first
series, the second series came to an abrupt end thanks to the writers
strike and the third season has struggled to get positive reviews.
I wonder how much longer NBC will stick with the show, which reportedly costs well over $4 million an episode.
UPDATE: The New York Times reports on NBC's attempts to save HEROES from sliding any further.
The impetus for the firings came from the top, according to two people
close to the production who spoke on the condition of anonymity. (These
and others close to the show were not authorized to speak on the
record.) They said that Jeff Zucker, president and chief executive of NBC Universal
and Mr. Silverman’s boss, was greatly upset by an Entertainment Weekly
cover story two weeks ago that said some of this season’s developments
were “jump-the-shark preposterous” and concluded that the series “may
no longer be a pop-culture phenomenon.”
[…]Yet on Friday, Entertainment Weekly also reported that Bryan Fuller,
one of the lead writers in the first season of “Heroes” who left to
create “Pushing Daisies” for ABC, is considering a return to “Heroes”
if ABC fails to extend “Pushing Daisies” beyond the 13 episodes it has
ordered for this season.
