Nielsen Media Research said today (Monday) that it is delaying the release of all primetime program ratings from last Friday through this coming Thursday following the Friday's switch from analog to digital television. "The 'hold' will allow us to ensure that there is sufficient time to fully validate data prior to release," Nielsen said in a statement. The delay affects release of ratings for Sunday night's ABC telecast of the final NBA match between the Lakers and the Magic, won by the Lakers 99-86. TV columnist Hal Boedeker, who writes for the Magic's hometown newspaper, the Orlando Sentinel ,commented, "The delay is kind of strange because the shift to digital television seemed to go off without a hitch." However, the FCC reported that Chicago's ABC outlet, WLS-TV, experienced operating power issues on Friday that prevented the NBA telecast from being seen in some downtown areas and high-rises. Likewise, it was reported that the FCC received numerous calls from Philadelphia where people claimed that they were unable to receive WPVI's digital signal. Broadcasting & Cable magazine quoted FCC staffer Bob Radcliff as saying that the commission is conducting field tests on why certain stations "are experiencing problems in big cities" and how to "adjust the technical parameters of these stations."
