WORC is a radio station broadcasting on 1310 AM from Worcester, Massachusetts, and is owned by Gois Broadcasting. The station broadcasts at a transmitter power output of 5,000 Watts during the day and 1,000 Watts at night, and serves central and eastern Massachusetts. Since January 2005, the station has been broadcasting full time in Spanish with a tropical format. The station is the only full time Spanish-language station serving central Massachusetts, especially Worcester's rapidly-increasing Latino population. A one-time affiliate of both the CBS and ABC radio networks, WORC from the 1960s until the mid-1980s (with the exception of a few years in the early 1980s when the station briefly programmed country music) was a Top-40 outlet. It was an oldies station in the early 1990s, as well as country in the mid-1990s, then was a talk station before adopting its current format.
