If I remember correctly from a few weeks ago, Zynga revenues increased and most of their spending remained flat, but they've increased spend on R&D dramatically hence why they are showing lower profit figures. This is a smart move, in my opinion. You can lead a market by being good at capturing it early on, even if you simply just copy other people's ideas, but to remain there or go beyond that requires innovation especially as competition increases or the nature of the market changes.
