One of this year’s most important meta-stories has been regulators’ increasingly effective pushback against seemingly unstoppable tech giants.  We’ve had three examples in the past week, starting with Amazon’s agreement to reduce the advantages it gives to its own products and stop helping itself with data it collects about sales by independent merchants.  Both changes are in response to European Union anti-trust activity and presumably apply only within Europe.

Most potentially impactful of all, Apple is reportedly planning to allow third-party app stores on the iPhone.   Sellers could presumably bypass Apple’s 30% commission on payments, a sore point for many and huge profit source for Apple.  Apple has faced some pressure about this in the U.S., where iPhone market share is much higher than elsewhere.  But new EU regulations are what’s forcing the change.

T-Mobile will allow advertisers to target more than 20,000 screens in 11,000 store locations. That’s a lot of screens, but how much foot traffic does the average T-Mobile store get? It’s also linking up with streaming media company Plex as a CTV partner.
