Diane Haithman is contributing to Deadline’s TCA coverage.

In his opening remarks before today’s TCA panels on Netflix‘s first slate of original programming, Ted Sarandos, Netflix chief content officer, announced a debut date for Eli Roth’s one-hour murder mystery Hemlock Grove (April 19). Sarandos said the fourth season of Arrested Development will begin airing in May with “all 14 episodes at once,” confirming our story that the 10-episode order of the cult show’s reboot has been expanded. The executive said Netflix will launch “all episodes of all of our series at the same time in most of over 50 territories and countries where we operate” in an effort to “program for the on-demand generation.” Next up is original drama House Of Cards, which premieres February 1.
