In announcing the pickup Thursday, HBO said: "Together they set out on a patriotic and quixotic mission to do the news well in the face of corporate and commercial obstacles and their own personal entanglements."

Sorkin, an Oscar winner for adapting the Academy Award's 2010 Best Picture winner The Social Network, wrote ABC's Sports Night and NBC's Emmy-winning The West Wing; he will executive-produce the upcoming series along with Scott Rudin and Alan Poul.
