Hey, Delphi (aka Object Pascal) is 12th - that's not bad, though its ranking is falling. :-( But again, look at that spike back in 2005. Just shows what new management can do.

Good old Pascal (procedural non-Object Oriented one) is not doing bad either, sitting steady at 15th place.

Wow, here are some interesting graphs for you.
This one just goes to show what a populare product(s) like iPhone and iPad can do to the popularity of a programming language. http://www.tiobe.com/index.php/paperinfo/tpci/Objective-C.html

And what's up with Ada? Moving up 12 places from last year. I thought that language was done and dusted, or maybe I got confused with another language.

Visual Basic! Wow, is anybody still using that?? It's falling fast, but still up there in 5th place!

What new management? CodeGear was announced by the beginning of 2006 and Delphi was sold in 2008. However I admit, I cannot give any reason for the spike in 2004/2005. I noticed it already years ago and didn't find any reason so far. By the fall of 2004 Delphi 2005 was release, but why should it cause such a peak?

There is one simple reason in Tiobe's FAQ:

Q: What happened to Java in April 2004? Did you change your methodology?

A: No, we did not change our methodology at that time. Google changed its methodology. They performed a general sweep action to get rid of all kinds of web sites that had been pushed up. As a consequence, there was a huge drop for languages such as Java and C++. In order to minimize such fluctuations in the future, we added two more search engines (MSN and Yahoo) a few months after this incident.

Ok, then I must have gotten my dates wrong. It is weird though.

Between Delphi7 (1999/2000) and Delphi2005 there was Delphi 8. That was a .Net only Delphi and probably THE most crappy product Borland ever released. The news of a new win32 supporting compiler spurred a new wave of Delphi renewals. Almost everyone was disappointed afterwards until Delphi2007 became a somewhat decent successor again. That is was caused the spike. Most companies I know that have tried 2005 downgraded again to D7 (in fact, not officially through a downgrade program). Actually, some of them are STILL using D7 at this moment. (11 years old)

kind regards,

The company I work at is still using Delphi 6. :) But I'm currently porting our whole software to Delphi 2007 (no, we don't want to fiddle around with Unicode-VCL :P ).
