Video-sharing site YouTube.com's audience spiked from 624,000 for the week ended Dec. 18 to 2.3 million for the week ended Jan. 1 after it carried a Saturday Night Live "Lazy Sunday" rap-video skit spoofing two geeks' day at the movies, reports AdWeek. NBC released the clip to YouTube, iTunes and others, where bloggers linked to it. YouTube, which began operating in February, is now the fastest-growing video site online, according to Nielsen//NetRatings. Its monthly visitors more than doubled from October to November, reaching 1.1 million in November.
In November 2005, Sequoia Capital, an early Google backer, invested $3.5 million in YouTube.
