"This table contains a list of major software products or utilities, with details about the programming languages used to implement them. Information on this is difficult to find, and a few small mistakes might have escaped the author's attention. Corrections, suggestions for additions or even references are welcome. The list is not supposed to be exhaustive but the most significant products are tentatively listed. The order of the products in each family obeys no specific rule, the reader should not understand it as a ranking.
The main programming language, the one with which most of new developments are done, is highlighted, while the ones used in older times and still present, or used only for a minority of the developments are indicated too. The pieces of software listed are usually very large, and the list of programming languages cannot be exhaustive. Miscellaneous languages are not mentioned. Sometimes, there are different products under the same line (eg "Games"), or different implementations of a single line (eg JVM implementations). In this case, the overwhelming trend is indicated. Miscellaneous counter examples are ignored.
Some readers believe that most of the applications presented are based on old code, and that the technologies in use reflect the trends of the time. As it is an erroneous belief, some introduction dates are mentioned, like here, or here to show that what is "new" or "old" technology does not necessarily correspond to intuition.
The difference between C and C++ is a bit artificial, as it is always possible to argue that most of C code is C++ code, or conversely (as more than a few people use C++ more or less like C). The approximation made in this document tries to correspond to intuition."
