I don't think the popularity of a programming language could be measured by how many hits it has on search engines. For example, it may well be that 50% of those hits are forum posts from people being frustrated because the language sucks. In addition, the fact that a language is in use in a lot of existing systems says little about when that code were written, and which options were available at that time.
