Chart of the day: Amazon beats Samsung in U.S. tablet salesMarch 21, 2013: 7:01 AM ET
According to ComScore, Kindle Fire outsells Samsung's Galaxy tablets 4 to 1 in the U.S.
Apple (AAPL) maintained its position as the No. 1 tablet manufacturer, but in battle for dominance among the Android tablet makers in the U.S. market -- which is what ComScore is measuring here -- Amazon is crushing Samsung.
In the worldwide market, where Amazon has a far smaller presence, the relative positions are reversed. According to IDC, Apple was still the leader with a 43.6% share of shipments in Q4 2012 , followed by Samsung (15.1%) and then Amazon (11.5%).
Take these estimates with a grain of salt since Samsung no longer reports sales or shipment numbers and Amazon never did.
