Wall Street Journal: Amazon, for the first time, is offering its parcel boxes as advertising space. In a deal with Comcast’s Universal Pictures and Illumination Entertainment, the online retailer is packing shipments in bright yellow boxes decorated with characters from the coming movie cartoon “Minions” until the film’s release on July 10. Customers have started posting photos of themselves with the colorful boxes on social media, part of a hashtag sweepstakes from the companies to win a $1,000 Amazon gift card.
