A Ratings Reprieve for the Networks April 23, 2012, 3:59 pm After plummeting to new depths in the ratings last week, the broadcast networks were granted a small reprieve on Sunday. According to Nielsen's estimates, overall numbers were up when compared to last week's in both total viewers and in the a18-to-49-year-old demographic coveted by most advertisers. ABC in particular received some positive news, its second Hallmark Hall of Fame film, "Firelight," drew 7.6 million total viewers, an improvement over the 6.5 million that watched the network's first Hallmark movie last fall, "Mitch Albom's Have a Little Faith." "Once Upon A Time" (also on ABC) was up slightly when compared to its last new episode from three weeks ago, from 8.36 million total viewers to 8.84 million. Elsewhere, Fox was in a celebratory mood as it started the night with the original pilots for "Married... With Children" (3 million total viewers) and "The Simpsons" (3.2 million) and finished with the two-hour "Fox 25th Anniversary Special" (4.3 million).
