A short “look what I bought” video, often posted on YouTube, in which a young woman displays the fruits of a shopping expedition.
The term showed up on Yahoo! Answers sometime in 2008 and finally hit the mainstream in 2010 with articles in the New York Times and coverage on NPR. A blog, HaulVideos.net, aggregates some of the most popular haul videos. And nothing confirms a trend like a parody: HaulBlog (“Making the world more stupider, one video at a time”), was launched in March by three Southern California dudes who post videos about 3D glasses, razors, and Thanksgiving leftovers; a recurring feature is called “The Haul Monitor.”
