Fringe's ratings for its first two weeks on Fridays had sort of the feel of the Kansas City Royals winning 20 games in April and then swooning by June. Last night was the first Friday where Fringe had to compete with original programming on all the other broadcast networks so the drop from a 1.9 adults 18-49 rating to a 1.6 adults 18-49 rating isn’t that surprising.
Fox broadcasting entertainment chief Kevin Reilly has been quoted saying that if Fringe kept 100% of its Thursday ratings it would be a big win for FOX. But then he was quoted using 90% and 80%. If you take Reilly at his word on the lower end, and don't think Fringe will fall much more (the 80% level would be about a 1.5 adults 18-49 rating), then there's no need to worry yet.
On the other hand if you're a tea leaf reader and reading the leaves thrown down by Fox's semi-anonymous head of scheduling in a tweet this morning, it's not too early to worry:
Uh Fringe-o-philes you gotta stay with the program. FOX NBC and CBS tie for the night in 18-49's. Fringe takes a dip.
