Soon Hulu will look more like a traditional network than an Internet pioneer. At a presentation in New York, Hulu, created as a service for watching network television online, will pitch advertisers on original programming in an annual ritual known as upfronts that are typically reserved for cable channels and network broadcasters. Hulu executives are expected to take the stage to sell advertisers on new series. The executives will also promote the service’s desirable demographic of young viewers who turn to Hulu for popular network sitcoms like “New Girl” and “Family Guy,” available only after they are broadcast on Fox.

As an online television destination, Hulu is something of a teenager now, sometimes tolerating feuding parents and succeeding perhaps in spite of them. Hulu is growing steadily, despite disagreements among its corporate owners, and the new restrictions those owners have placed on free streaming of network shows. This week Hulu will announce that it has topped two million subscribers for its $8-a-month Hulu Plus service in the first quarter, half a million more than it had at the end of 2011. But it has not been an easy path to growth.
