Obviously pleased with the success they’ve had so far this year, ABC has already announced that two of its shows will be picked up for a full-season:  Commander in Chief and Invasion.  While Commander in Chief has obviously been a runaway hit for the network (it placed 9th in the Nielsens last week), I can’t imagine that Invasion would be able to survive without ‘Lost’ as its lead-in.  Nevertheless, ABC should be pleased with any success they can get, no matter how they achieve it.
