EachMovie Data Set
HP/Compaq Research (formerly DEC Research) ran the EachMovie movie recommender. When EachMovie was shutdown, the dataset was available to the public for use in research. MovieLens was originally based on this dataset. It contains 2,811,983 ratings entered by 72,916 for 1628 different movies, and it has been used in numerous CF publications. As of October, 2004, HP retired the EachMovie dataset. It is no longer available for download.
