I came across this year-end report on TV viewership -
Most-Watched Television Networks: Ranking 2018’s Winners and Losers- and noticed that Decades doesn't even show up in the chart rankings at the bottom of the article. Now, perhaps for some reason Decades wasn't considered. But if it doesn't show up because its viewership is even lower than Comedy TV, which has only 1000 viewers, well, then Decades is really in trouble...
