Over the course of 2011, investors steadily unloaded their holdings inResearch in Motion (Nasdaq: RIMM) as it became apparent that the maker of Blackberry phones couldn't keep up with the tag-team onslaught of Apple (Nasdaq: AAPL) and Google (Nasdaq: GOOG), which now collectively control more than 75% of the global smartphone market.
Perhaps an even greater victim of the Apple/Google juggernaut has been Nokia (NYSE: NOK), which should have been an important player in the smartphone market.
