Hartz Mountain Industries

Hartz Mountain Industries (HMI) is a private family-owned-and-operated company known for its real estate holdings in the New York/New Jersey Metropolitan Area.

Max and Gustav Stern emigrated from Germany to the United States in 1926 with five thousand singing canaries (Harz Roller), and began manufacturing bird food under the Hartz Mountain brand in 1932.

In December 2011, the Japanese pet and household products maker Unicharm acquired 51% ownership of HMC from Sumitomo.

HMI currently owns more than 1,800 acres (730 ha) of land close to Manhattan[citation needed] and its real estate activities account for most of its business.

[citation needed] Among the properties it owns are the studios for MLB Network (formerly used by MSNBC) and the land on which WWOR-TV's broadcast facilities sat prior to consolidating with sister station WNYW in Manhattan.
