After a busy week down in Washington D.C., Facebook's Mark Zuckerberg seems open to regulations -- while the social media giant continues its own efforts toward a more transparent ad ecosystem.

I think this would be very good if it’s done well,” Zuckerberg said on Facebook’s Q3 2017 earnings call. “And even without legislation, we’re already moving forward on our own to bring advertising on Facebook to an even higher standard of transparency than ads on TV or other media.”For the First Time, More People Will Do Their Holiday Shopping On Mobile Than Desktop [Recode]If you visit a U.S. retailer’s website this holiday season, you’re most likely to do so on a mobile device. More than half of visits to shopping sites — 54 percent — will come from smartphones and tablets, surpassing desktop computers for the first time, according to Adobe Analytics’ annual suite of online holiday retail predictions. Customers are still more likely to actually complete a purchase on desktop after looking on mobile, but that’s changing.How Publishers Are Getting Fooled by Ads.txt Fraud [Digiday]Publishers say that third-party sellers like Thrive+, Ludius Media and SelectMedia asked to be listed on their ads.txt files, even though the publishers did not have direct relationships with these companies. These vendors say they were merely trying to approach new business partners or form direct relationships with publishers whose inventory they were already reselling.Grubhub’s New Ad is Designed Like an Old-School Video Game to Get You to Order More Food [Business Insider]"So much of advertising today is a passive experience, and we really wanted to make ours a sticky and engaging experience," Mallorie Rosenbluth, the head of social media at Grubhub, told Business Insider. "We wanted to take control as the brand, make this a real engagement play, and get a true sense of how much time our consumers spend with the game, interact with it, and also reward them along the way."‘It Can Be Good to Have a Big Stick’: Thanks to Google, Ads.txt is Taking Off [Digiday]Google isn’t alone in pushing for ads.txt, so it can be difficult to separate correlation from causation when trying to determine what prompted so many publishers to create ads.txt files recently.

Ad Blocking, its Impact and What Comes Next [MarketingLand]Something I’ve seen lately are publications that attempt to trick ad blockers using various techniques. One maddening method I ran into involved about 20 to 30 separate scripts running that would auto-load and insert ads if one happened to get blocked. This was set up on a news site.
