If sales were still slowly on the decline after that, the only thing that really could be to blame was content, if the original fans were slowly dropping titles.
The other factor that doesn't get addressed by that line of reasoning is market segmentation. This hit first run syndication programming on TV and table-top Role Playing games too.
