In March 2007, The Onion launched The Onion News Network, a daily web video broadcast that had been in production since mid-2006. The Onion invested about $1 million in production and hired 15 staffers to focus on the venture. ONN was the only scripted comedy series in the US to employ non-union writers. The writers unionized between Seasons 1 and 2 in the midst of a strike threat.
