Scott Galloway presents the week's biggest winners and losers in digital:
Winner: Snapchat. No longer just an app, the company aims to reinvent the camera with Spectacles, its new hardware product.
Loser: Warehouse clubs like Costco and Sam's Club, which are rapidly losing share to Amazon Prime.
Loser: Fashion insiders. As brands adopt the see now, buy now format and post on Instagram and Snapchat, fashion executives need to keep pace with the changing times.
Winner: Google, which recently celebrated its 18th birthday.
