"The climb of Chrome during 2011 has been astonishing," remarks Computerworld. "It has gained eight percentage point since January 2011, representing a
50% increase." During that same timeframe, Firefox has dropped almost four percentage points -- a decline of about 13% -- while IE has also fallen four points -- a 9% decline.
In other words, rather than the proverbial pie getting bigger, "Chrome is essentially reaping all the defections from Firefox and IE." As Computerworld notes, however, disparate data paints a different picture of Chrome's current market position. Net Applications, for one, reported that Firefox had a 22.6% share of desktop browser usage in August, compared to Chrome's 15.5%.
