K·B Toys were the exclusive retailers of Kenner Products' Aliens: Hive Wars toy line. At its height, K·B Toys operated 1,300 stores across all 50 states. The company went out of business in 2009, and international retailer Toys "R" Us acquired it remains, consisting mainly of its website, trademarks and intellectual property rights.
