Lol a few years ago I did a full-page capture of a web article. 60% of space is just ads, with actual content sprinkled among the minefield. The rate has only worsened since then.
That's about the traditional ratio of the adverts-to-newshole in newspapers.
In the past few years, the (very much suffering) principle local daily began falling far below this level. During the first wave of COVID-19, there were days with virtually no advertising at all.
On the one hand, that made for less distraction. But knowing that ad revenue is the mainstay of newspaper revenues, it was terrifying. The bleeding has continued, and the household eventually cancelled its subscription (something I'd long advocated for).
