S3 Texture Compression
A group of lossy texture compression algorithms originally by S3 Graphics included in DirectX 6.0, OpenGL 1.3, and subsequent versions.
Alternate names: S3TC, DXTn, DXTC, GL_EXT_texture_compression_s3tc, GL_EXT_texture_compression_dxt1
The first video game about S3 Texture Compression was released in 2004.
To date, the patent is not valid outside the USA. A Debian based solution for anyone not bound by the patent are the libtxc-dxtn-dev and libtxc-dxtn0 packages.
Apparently during the HTC-Apple legal battles in 2011, the S3TC patent was pronounced invalid. However, only Intel and X.org have acted on this news. Google seems to be skeptical that this news is true or that the patent is in fact invalid.
