During the summer of 2006, YouTube was one of the fastest growing sites on the World Wide Web,[11] hosting more than 65,000 new video uploads. The site delivered an average of 100 million video views per day in July.[12] It was ranked the fifth-most-popular website on Alexa, far out-pacing even MySpace's rate of growth.[13] The website averaged nearly 20 million visitors per month according to Nielsen/NetRatings,[12] with around 44% female and 56% male visitors. The 12- to 17-year-old age group was dominant.[14]YouTube's pre-eminence in the online market was substantial. According to the website Hitwise.com, YouTube commanded up to 64% of the UK online video market.[15]
YouTube entered into a marketing and advertising partnership with NBC in June 2006.[16]
