From a Reuters story on Kevin Reilly, president of NBC who was speaking at the Television Critics Association Winter Press Tour in Pasadena, Calif. :
"And he said "The Book of Daniel," starring Aidan Quinn as a pill-popping Episcopal priest who talks to Jesus, might be yanked before running its full six-episode course. The show has drawn weak ratings and misgivings from some advertisers and affiliates."
And this from tvweek.com:
"Calls for an advertiser boycott by groups such as the American Family Association of NBC's Friday night drama "The Book of Daniel" did not have a direct impact on ad sales for the series, Mr. Reilly said. "You let the audience vote," he said, noting that if the show attracts more viewers, advertisers would be less likely to be concerned about controversy."
