Nielsen Thursday disclosed yet another software glitch -- this one impacting four-months of data related to its weekly syndication all-minute respondent-level data file.

"Due to a software complication that has been identified and resolved, historical commercial volumes of the weekly syndication all-minute respondent-level data file for the weeks of December 20, 2010, through April 17, 2011, excluded the commercial minute data for some telecasts and have been reissued," Nielsen stated, adding, "All other Nielsen systems that report individual and average commercial minute data for Syndication are correct and complete."
