THE PAJAMA SHOPPING REVOLUTION? Black Friday store spending edges up; online soars.

Shoppers who endured long lines and sometimes-frigid temperatures spent only slightly more during their Black Friday shopping sprees than they did last year, according to data released Saturday by a research firm.

At the same time, their pajama-clad counterparts, a much smaller group that accounted for only a fraction of overall sales, shopped online from the warmth of their homes and dramatically boosted their spending.

And yet online advertising was down last quarter.
