When Verizon renegotiated the AOL & Yahoo search deals with Bing / Microsoft I think Verizon gained some control over many of the display ads shown on MSN.
But as broadband speeds improve & computers get more powerful the types of content people consume online change. Text then images then videos. And there are a lot of MMORPGs these days.
Video games are going to be a huge online ad category. They already are for Apple, Google & Applovin.
In a prior quarter Sundar Pichai spoke of Google Play ads as though it was primarily an ad program for games & gaming. Google also signed a deal with Unity & changed how advertisers could block having their ads shown in mobile apps.
The newest version of Xbox does not even support game discs.
So many of the former reasonable pay-once mobile apps are now subscription only (while requiring harvesting lots of user data at hello). Those will only make the ad-powered competing apps seem relatively more appealing. As much as people hate ads, almost nothing is worse than managing a hundred automated recurring subscriptions.
Google advertises on the web and on gmail, I wonder if this name change is a precursor to MS advertising on Outlook or Office :)
The free version of Outlook does have ads in the right rail.
Google stopped using all the personally targeted & contextual data for deeply relevant ad targeting in Gmail because those ads were making it harder for them to sell their Microsoft Office competitors to enterprise-level clients.
