Online comedy is a lot harder than it looks. Officials at NBCU have said they will kill DotComedy, an online destination launched a little more than a year ago. According to a MediaWeek report, the site failed to attract an audience, twice dipping below Nielsen's online minimum threshold for reporting.

NBCU, which will redirect the content to its newly launched Hulu joint venture, joins Comedy Central as the latest stalwart to struggle with its digital transition. Earlier this week, Comedy Central said it would shift its content, which includes "The Daily Show," to AtomFilms as part of an effort to rebrand itself for online comedy.

NBCU had hoped that the mix of new content with footage from "Saturday Night Live" and "Late Night with Conan O'Brien" would lure a devoted online audience. But while the content remains popular, most viewers tend to find it on YouTube.
