Poor CW. It hasn't even hit the tube yet and already another network is stealing its thunder. Fox announced yesterday that on Sept. 5 it will launch offshoot channel My Network, which will broadcast original programming from 8 to 10 pm/ET, Monday through Saturday. Among the new series My Network is hyping are Desire and Secrets, a pair of prime-time soaps, which, like Spanish telenovelas, will air one episode per weeknight for about 13 weeks apiece. My Network is very proud of its sudsers. My Network is giving them a big push. My Network is really fun to say. Go ahead, try it. Leslie Moonves, you have been warned.
