I did a market study for my parish in the mid 1960s and only 25% of those receiving the bulletin ever read them.
The percentage probably hasn’t gotten any better now, but reading major sections of the bulletin is a waste of time.
I’m not sure how announcing that the All-U-Can-Eat Spaghetti Dinner hosted by the Knights of Columbus is coming up on Friday...5 bucks apiece and no more than 20 bucks per family...contributes to the liturgy.
OTOH, I could just zone out for a couple of minutes and read the bulletin on the way.
