Last week (Feb. 26 to March 2), CNBC had its best week in its Business Day time period in the key 25-54 demo since the week of September 17, 2001 — the first week of trading after 9/11. CNBC’s Business Day programming runs from 5am to 7pm Monday through Friday. The net averaged 128,000 in the demo for the week.

Several network shows had their best week ever in the demo, including Kudlow & Co., Mad Money, and Fast Money. (Those shows premiered after 2001.)

As always, CNBC notes that Nielsen doesn’t accurately measure its viewership because it “does not include ‘out-of-home’ viewing in places like offices, restaurants, health clubs and hotel rooms where CNBC has significant viewership.”
