It's been coming along for some time, but today RPM Fusion has officially launched as the premiere third-party RPM repository for Fedora and Red Hat Enterprise Linux (RHEL) users. The Dribble, FreshRPMs, and Livna repositories had merged to form RPM Fusion. Found in this massive third-party repository are RPM packages that can't ship with Fedora or RHEL due to legal restrictions and/or the packages don't comply with free software licenses.
Among the packages available through RPM Fusion are the binary-only ATI and NVIDIA graphics drivers, proprietary audio/video codecs, a number of different games, emulators for different gaming platforms (such as SNES) as well as older computer platforms, and many other packages. The announcement marking the public availability of RPM Fusion was made on the Fedora mailing list
