The annual awards ceremonies were held simultaneously on both coasts Saturday evening to honor creators of the best film, television and variety show scripts.
Oscar favorite "The King's Speech" wasn't eligible for an award because of union rules, The Hollywood Reporter said. Christopher Nolan's "Inception" script defeated several favorites including "The Fighter" and "The Kids Are All Right."
Aaron Sorkin won the adapted screenplay award for "The Social Network." His script also won a Golden Globe for best screenplay.
AMC's "Mad Men" won the television drama series and ABC's "Modern Family" won for comedy series.
Writers from HBO's "Boardwalk Empire" won the award for best new series and Robert Carlock won the prize for episodic comedy for an episode of "30 Rock." Erin Levy won an award for episodic drama for a "Mad Men" episode called "The Chrysanthemum and the Sword."
Winners in the documentary category were Chad Beck and Adam Bolt for "Inside Job."
