For the fourth week of the season -- ending Oct. 17 -- CBS dominated the prime-time household ratings race with the top two shows and seven of the top 10, retaining a commanding lead while continuing to hold on to first in the 18-49 demo.
But ABC made gains in 18-49s, regaining the top spot from CBS's CSI and placing four shows in the top 10, up from three the previous week.
The ABC show moving up in the 18-49 demo was Lost, which went from the twelfth spot the prior week to number 10. CBS and ABC tied for the most shows in the top 10 in the demo with four apiece. NBC had two.
