●＜規模の比較＞フェースブックがまもなくヤフーに追いつく！！？

　グローバルな参加者数はヤフーの月間（２０１０年７月）622百万人に対してフェースブックは572百万人です。グローバルな差は既に５千万人です。

　ページビューは既にフェースブックが２倍、しかし広告収入はヤフーはフェースブックの４倍稼いでいます。

　差が詰まって来ました。

　★★The Inevitable March of Progress: Facebook Soon Will Have More Visitors Than Yahoo

　　http://techcrunch.com/2010/08/24/facebook-more-visitors-yahoo/

In terms of pageviews, Facebook is already more than twice as large as Yahoo, with an estimated 250 billion pageviews a month, versus 96 billion for Yahoo (see chart below). With pageviews comes advertising dollars. Facebook is expected to take nearly 40 percent of the $3.3 billion in social networking advertising dollars estimated to be spent this year. That would still make it about one fourth the size of Yahoo in terms of revenues, which was $1.6 billion for Yahoo last quarter. But Facebook is only just now figuring out how to target advertising across its network.
