European countries' media systems are very different from the US and your conclusions are not really valid.

The ZDF, one of these PSBs, reaches an average of 5 million people daily on TV, which accounts to >10% of the German TV audience, and it has an online reach of >100 million monthly visits which also makes it one of the top news sources online. Their audience leans towards elderly segments, but it's still a huge chunk of the market, however you may define it.
