It's called LZW, which stands for Lempel, Ziv, and Walsh.  (Lempel and Ziv wrote the original paper, and Walsh published a subsequent version.)

I'm sure Mrs. Welch will be surprised to hear that Terry has changed his surname. Luckily, this error doesn't effect the correctness of tom's answer since WinZip's algorithm for maximum data compression is a hybrid of LZ77 and Huffman coding known as 'Deflate'. LZW (Lepmel-Ziv-Welch) coding is patented by Unisys, Deflate is (as far as I know) public domain.
