Scott Galloway presents the week's biggest winners and losers in digital:
Winner: Amazon shareholders. The e-tailer's new grocery stores confirm our predictions that the company would open brick-and-mortar locations in its ambitious bid to dominate retail.
Winner: Stripe, the world's second-largest digital payments company. Half of Americans have used it to make a purchase in the past year, although most probably don't know it exists.
Loser: Newspapers. Social media ad spend will surpass newspaper spend by 2020 - but we're already seeing evidence of ad fatigue.
Winner: HBO, which set new viewing records with the season finale of Westworld. Here's a preview of our spinoff, Scottworld.
