comScore Networks has reported the latest worldwide ranking of top Web properties, ranked by unique visitors aged 15 or over, per month.
It says: "Of note were the gains experienced by Wikipedia Sites and Youtube.com during September. Both sites were up 12 percent versus August."
Time Warner Network is mainly AOL. I assume Fox Interactive Media includes MySpace. Viacom Digital includes MTV.com, VH1.com, Nick.com etc, Neopets and Xfire.
