All it took was one episode.

A couple days after its critically-acclaimed series premiere, Treme has been renewed for a second season.

The decision is a major leap of faith by HBO, as the Sunday night episode only drew 1.4 million viewers in its combined airings.

But HBO president Michael Lombardo has no doubt about the move. He told The Hollywood Reporter:

"We would have picked up this show last week. We've seen the first nine episodes it's as strong as any show we've seen. Much like The Wire, the audience is so passionate and so invested. We're about servicing our subscriber base and I believe that people will become addicted to this show. We have to be a place where this kind of excellence is given space to continue."
