I like that too, but I’m glad someone else pointed it out. Somewhere I have a blog post about labeling the last point of each series in the chart with the series name, so today’s labeling is a variation on that theme.

Very good point. I alluded to other news outlets (web sites, blogs) but didn’t take into consideration overlap. It’s possible the survey results asked for the respondent’s primary news source. But to be save, the line chart showing audience numbers (which was my favorite anyway) is the one to rely upon.

I like the way your line chart and stacked bar chart reports the name in the first point/bar and then the actual movement of market share in the 2nd point/bar. Nifty.

For “Audience Size”, I like the line chart, but am leery of the stacked bars.

That is because they give a total audience number close to 100 M when I suspect that the overlap among NPR listeners, newspaper readers and TV viewers gives an audience number significantly lower.
