That's in lieu of watching the normal Hulu commercial load of about four 30-second ads in a 22-minute program, according to data from Hulu.
Though the long-form opt-in ads appear on the site only occasionally, the early data indicates viewers want to control the kind of ads they see in the shows they watch online. The high opt-in rate also suggests that because consumers are selecting the ads, they are more likely to be engaged with them.
"The opt-in rate is proving this is something people want," said Christina Lee, a Hulu spokeswoman. Advertisers buying long-form ads on Hulu include Columbia TriStar, American Express, Hyatt, Paramount Pictures, Sprint and Capital One.
The format doesn't work for every marketer, but both Hulu and media executives are encouraged by the early success.
"We are trying to break down a lot of these very traditional ways of thinking about advertising, so this is a way to experiment and an example of something you'll see us doing," Ms. Lee added.
The Hulu data also bolsters two commonly held advertising beliefs—consumers aren't averse to ads and they do like choices, said Lori Schwartz, senior VP and director of the Interpublic Emerging Media Lab.
"What consumers don't like is being stuck watching long pre-rolls or being forced to participate and being forced to watch stuff that isn't relevant," Ms. Schwartz said. "When you give them a choice, you are thinking about them, and that gets them excited. We are in this culture now where people expect participation and expect to be included and expect two-way communication to happen."
