If you look at the raw charts then you can see that C++ has been in decline since about 2005 and Objective-C has shot up to overtake it with amazing growth. But the two charts are on different scales — if you plot both on the same chart you can see that rather than rocketing up Objective-C has just crawled its way passed and it is as much to do with the decline of C++. It simply hasn't reached the popularity of C++ in its heydays before 2005.
However the real story is that C, a raw machine independent assembler like language, with no pretense to be object oriented or sophisticated has beaten all three of the object oriented heavy weights — Java, C++ and Objective C.
Yes C is number one (and a close second in the transparent index).
Now this is something to think about...
