Newspapers here in Australia will have those catalogue inserts (we don't really have coupons) PLUS ads on almost every page. In fact, the amount of pages in the daily newspapers is directly decided by the ad inventory they have - fewer ads and they'll leave out content, more ads and they'll find more stories or lower the bar a bit.
Yes, but the advertisements don't get in the way of the content - editors wouldn't allow that. Also, the only way the ads can harm you is if they're coated with cocaine or some other drug :)
I suggest you pick up a copy of the New York Post and other NYC 'tabloid' style papers before making a blanket statement like "editors wouldn't allow that."
I could, yes - but I was lightly referencing the fact that opening up a newspaper and seeing an ad that I don't care for means I can move past it or ignore it, whereas with a computer it could mean having to spend time running a malware scan because the ad was hosted by a malicious provider.
Leaving me with 3 or 4 thin sheets of local news.
