Where have all the business ads gone?

I’m not saying the economy is bad and I daren’t use the “r” word, but in all my years of reading the New York Times Business section I don’t ever recall thumbing through an issue without ads. Perhaps September 12, 2001.  Today’s business section had not one page of display advertising. Not a half page. Not a quarter. Oon-gots (I apologize to my Italian readers for the spelling.)
Actually, there are three postage size ads touting churches and a cigar-size ad selling a book about the bull market, but that’s it. If businesses aren’t investing in advertising in arguably America’s greatest newspaper, we are in a serious downturn.
