The New Old Yahoo Under Marissa Mayer

Yahoo (YHOO-$38.23) continues to fall further behind Google (GOOG) and Microsoft (MSFT) in organic growth for inquiring eyes (and potential customer dollars). In June 2012, the respective share of the U.S. search engine market held by Google, Bing and Yahoo stood at 66.8%, 15.6%, and 13%; data released by comScore for December 2013 showed Google and Microsoft continue gaining voice at Yahoo’s expense: Google and Microsoft expanded their market shares to 67.3% and 18.2% -- while during Mayer’s tenure, Yahoo’s market has fallen further to a 10.8% share.

Revenue slumped for the fourth consecutive quarter at Yahoo, dipping 6% to $1.27 billion in the last three months of 2013, led by a similar 6% decline in all-important display-ad sales to $491 million (as a price-per-ad decline of 7% offset a 3% increase in total number of ads).
