These design goals and the fonts' broad availability made some of them extremely popular with web designers. However, these proprietary fonts (or some of them) are not distributed with some modern operating systems by default (e.g. in Android, Ubuntu, FreeBSD, OpenBSD, OpenSolaris or some Symbian versions) and they are substituted by other fonts (e.g. by free software fonts, such as Liberation fonts, Ghostscript fonts, Droid fonts, DejaVu fonts and others). All of these fonts in their latest versions are installed by default in the latest versions of Mac OS X (i.e. Mac OS X 10.4 and newer), but older versions of Mac OS X did not install some of them by default (e.g. Andalé Mono, Impact) and old versions of Mac OS also did not include many of them (e.g. Arial). Some of these fonts are also not installed by default in iOS (e.g. Andalé Mono, Comic Sans MS, Impact, Webdings).
