For Apple, Google, and Microsoft, where does the money come from? Ed Bott has three graphs which show revenue sources for each. On Google:
Advertising revenues made up 97 percent of our revenues in 2009 and 96 percent of our revenues in 2010 and 2011
Then along came Motorola which dropped advertising revenue back into the 80-percent range. Now Motorola is gone and Google remains a one-trick pony. Advertising.
I’d like to see a similar set of graphs for profits.
