In 2006, a well known site conducted a study to compare the amount of clickthroughs and subscriptions using video hosting websites, such as YouTube and Google Video. They created 28 videos, which ranged from 15 seconds to 8 minutes long. However, all videos had a 5-second promotion at the end of the clip, specifying a website URL telling that the viewers might be interested on. Each video, which were personal and comedy in nature, included a link that drove traffic back to the main website.
