Apple announced that they did $10 Billion in the App Store last year with $1 Billion in apps just for the month of December:
Apple® today announced that customers spent over $10 billion on the App Store℠ in 2013, including over $1 billion in December alone. App Store customers downloaded almost three billion apps in December making it the most successful month in App Store history. Apple’s incredible developers have now earned $15 billion on the App Store. “We’d like to thank our customers for making 2013 the best year ever for the App Store,” said Eddy Cue, Apple’s senior vice president of Internet Software and Services. “The lineup of apps for the holiday season was astonishing and we look forward to seeing what developers create in 2014.”
Impressive numbers, though not necessarily to Wall Street where $AAPL is currently trading flat.
