We doubt Brian Williams is losing sleep over Onion launches, but with 400,000-plus plays during ONN’s first day, it should be enough to give Katie Couric pause.

Onion president Sean Mills told FBNY the early returns had been “fantastic,” and he was pleased, even though “we really tried not to have expectations.”

Headed by former Onion editor-in-chief Carol Kolb, the Network’s content is created by a staff of freelancers, as well as select Onion writers, and Mills says the programming will be diverse. “We launched a network, not a show. The breadth of the content is still to come,” Mills says. “We are going to be the people’s first source for news.”
