"The Social Network's" Trent Reznor and Atticus Ross won the Oscar for original music score at the 83rd Academy Awards on Sunday night. This was the first Oscar win for each composer. The duo also won the Golden Globe this year for their work on the film.

Reznor and Ross were competing against Hans Zimmer for "Inception," Alexandre Desplat for "The King's Speech," A.R. Rahman for "127 Hours," and John Powell for "How to Train Your Dragon."

The Academy Awards are taking place at the Kodak Theatre in Hollywood and are being televised live on ABC. We'll carry all the breaking news and reaction here on Awards Tracker.
