U.S. TV network NBC Universal is renewing its contract to broadcast sci-fi drama HEROES. The news comes just after the Writers Guild of America (WGA) members voted to end a three-month strike over Internet royalties - which has crippled the American TV and movie industry - earlier this week (begs11Feb08). It is reported the network plans to relaunch the popular series this autumn (08), along with other hit dramas such as Life and Chuck.
