Microsoft and Yahoo! are in merger talks, with Microsoft reportedly prepared to offer $50 billion for Yahoo, in a move seen as a challenge to Google’s dominance of internet advertising. Last month Google further entrenched at the pole position when it purchased branded placement experts DoubleClick for $3.1 billion. A merged Microsoft/Yahoo would still trail Google in search market share, who currently gets over 48% of all search requests.

MSN-Yahoo? Microhoo? Bah.
