Toys were fundamentally different than books, music, or movies. This time, there were no third-party distributors to provide any item and take back unsold inventory. The big toy makers carefully weighed how much product they would allocate to each retailer. And the retailers had to predict nearly a year in advance what the next holiday season’s most popular items would be, as a majority of their sales occurred within a six-week frenzy of parental indulgence.
