The last two television seasons have had it all. We've seen everything from the birth of a broadcast network (the CW) to the most debilitating industry work stoppage in 20 years. Now it's time to take a closer look at each of the five major broadcast networks and see what they are doing right, what needs improvement, and where they stand.

Kelly Hu completed the Honolulu marathon in her native Hawaii last month, and has the cast and crew of her new TV show to thank for getting her past the finishing line. The actress finished the race in just under five hours, and admits she can't believe how motivating and generous her friends on the set of medical comedy In Case Of Emergency were while she was in training.

Legendary actress Jane Seymour will guest-star in three episodes of the new ABC comedy series, In Case of Emergency. Her first episode airs Wednesday, Feb. 14 (9:30-10:00 p.m., ET/PT). Seymour will play Jason's mother, Donna.

* Courtney Cox stars in the FX series "Dirt," which centers on a tabloid editor and a photographer who try to make their way in the world of celebrity journalism. The network boasts some critically acclaimed shows such as The Shield, Rescue Me, and Nip/Tuck, so "Dirt" has large shoes to fill. The series premieres Tuesday, Jan. 2 at 10 p.m.
