....WebKit started as a fork of the KHTML and KJS libraries from KDE, and has since been further developed by KDE contributors (KWebKit), Apple, Google, Nokia, Bitstream, BlackBerry, Sony, Igalia, and others. WebKit supports macOS, Windows, Linux, and various other Unix-like operating systems. On April 3, 2013, Google announced that it had forked WebCore, a component of WebKit, to be used in future versions of Google Chrome under the name Blink.
Certainly Spain is pretty active in software developement (OpenSource and also proprietary), eg. Panda Security with the first cloud based AV which retrieved Malware definition in realtime from the cloud. Nowadays most other AV, even the Windows Defender, use this system.
