Below are the full weekly ratings results for the entire 1986-87 television season. Viewership wasn't reported by Nielsen until the fall 1988 season, so up until that point the only metric widely available was the household rating (which is what is reported here in this article). To calculate the estimated number of households watching, just multiply each rating by 874,000 as that is what 1 rating point represents. The following are clippings from Broadcasting Magazine and The Fort Worth Star-Telegram, which were two of the few publications in the United States to publish full weekly TV ratings results. Note: article clippings that did not include the date for that week's ratings were edited to include the dates.
