NEW YORK — Fox News Channel continued its reign during April, marking its seventh consecutive month on top in primetime ratings.

In primetime, Fox News Channel averaged a 0.7 rating (455,000 households), up 17% in ratings compared with April 2000, according to Nielsen numbers. CNN averaged a 0.6 rating (510,000 households), flat in ratings compared with last April.

CNN continued to top its nearest competish in households, but not by much, considering the 24-hour news net is available in nearly 20 million more homes than Fox News.

One upside for CNN: Larry King’s exclusive interview with Laura Bush from the White House posted a 1.8 rating (1.43 million households), making it the highest-rated cable news program of the month.

But, Fox News’ flagship show “The O’Reilly Factor” surpassed “Larry King Live” in both ratings and households for April. “O’Reilly” averaged a 1.2 rating (758,000 households), up 50% in ratings from last April even though Bill O’Reilly was on vacation for one week.

“Larry King” averaged a 0.9 rating (750,000 households), down 18% in ratings from last April. “O’Reilly” airs at 8 p.m. EDT, “Larry King” at 9 p.m. EDT.

Meanwhile, MSNBC averaged a 0.4 rating (250,000 households) in primetime, flat with last April. The net continues to boast it has the youngest viewing audience of the cable news nets in primetime, with an average age of 48 for the month, compared with Fox News’ 59 and CNN’s 62.
