The LZW compression method was first published in 1977. The use of LZW compression, and the 8-bit limitation, are what defines the .GIF format; it has always used this compression method. The .GIF format was copywritten in 1987, but I have no clue when exactly development of the format may have begun. As a side note, .PNG images also make use of LZW compression, are 24 bit, and are entirely unliscensed - Unisys owns at least part of the algorithm used to generate a .GIF image!

The LZW compression algorithm was part of the initial GIF87 file format, released June 15, 1987. GIF does not use straight LZW compression, by the way. It implements variable compression sizes, and codes for start and end of data.

The LZW compression algorithm was published by Welch in 1984 as an improved implementation of the LZ78 algorithm by Lempel and Zip in 1978. It became widely used in the GIF format in 1987.
