The 10 p.m. hour was the most popular across the board, and though FNC's total viewership eclipsed all of the broadcast nets -- ABC, CBS and NBC all aired an hour of RNC coverage -- the cable network was eclipsed by the younger-skewing NBC in the demo. NBC's 1.72 million adults 25-54 gave FNC its only real competition of the night, besting its demo showing for the hour by just 45,000.
