Still, writing about Dropbox or Facebook or Stripe or whatever is now hot is way more interesting for the journalists. However, there's no doubt that the guy who wrote nginx or the Unity team (the game engine, not the Ubuntu GUI) made a hell of an impact on the industry, too. It's just that it takes more technical expertise to actually appreciate what these guys have done. That's the reason why most of the people know Steve Wozniak (if at all) as "that guy who worked for Jobs." Not that Facebook or Dropbox or Stripe or Jobs don't deserve the praise, it's just that they've built their empires on technology that also does.
I've always thought that myself. It would be interesting if there were some statistics on that.
The Phusion Passenger application server is in C++.
Node.js is in C++.
For anything safety critical, C in particular still has a vice-like stranglehold in many industries (e.g. automobile)
Which is kind of ironic, given its well known foot-shooting abilities.
I see the desktop applications being swallowed up by C# at the moment.
In fact, it is my opinion that Qt is the one thing that keeps C++ relevant these days (http://weblog.jeroen.ws/blog/2012/11/19/how-relevant-is-c-pl...).
