'30 Rock' swaps places with 'Kath'

New NBC comedy to take 8:30 p.m. slot

NBC's new comedy series "Kath & Kim" is on the move again, this time swapping places with "30 Rock."

"Kath" will now air in the Thursday 8:30 p.m. slot, following "My Name Is Earl."

NBC originally scheduled "Kath" on Tuesday night back in April. In May, the network moved it to the post-"The Office" Thursday 9:30 p.m. slot.

"Kath," whose original order was recently upped from six to 13 episode, has been deemed more compatible with "Earl," which led to the switch to 8:30 p.m.

Based on an Australian format, "Kath" stars Molly Shannon and Selma Blair as brassy mother and daughter who prefer the finer things in life like acrylic nails, big hair and faux diamond chips.
