Programming languages used in most popular websites Source: en.wikipedia.org/wiki/Programming_languages_used_in_most_popular_websites

One thing the most visited websites have in common is that they are dynamic websites. Their development typically involves server-side coding, client-side coding and database technology. The programming languages applied to deliver such dynamic web content vary vastly between sites.
