After spending millions in advance on multibrand, in-store promotional deals with the National Football League, Procter & Gamble, Mars and PepsiCo, among others, now find themselves faced with the possibility of a truncated season that could do more damage to their plans and brands than those of the networks and TV buyers.
Networks can schedule alternate programming and marketers can apply media analytics to follow their target audiences wherever they go when they're not watching NFL football. But shopper-marketing events have calendars set a year or more in advance. Product has to be produced and displays have to be filled, regardless of whether games get played.
