Amazon declined to comment its plans for a toy catalog, which was first reported by Bloomberg, citing unnamed sources.

Paper catalogs have long been a part of the holiday tradition in the United States, going back to the Sears Roebuck catalog and later the JCPenny catalog. Both of those were superseded by the rise of the Toys 'R Us catalog, which for years reigned supreme as a wish book for kids in the lead up to Christmas and its presents. Walmart and Target also publish toy catalogs.
