Walmart said it will stop selling ammunition for assault-style rifles and handguns, further restricting its gun-related sales and policies after two deadly shootings in Walmart stores. CEO Doug McMillon again called for a debate about reauthorizing the assault-weapons ban. And both Walmart and Kroger also asked shoppers not to openly carry guns in their stores.

Former Representative Gabrielle Giffords applauded the move. “Walmart’s action is another sign that the private sector has had enough with America’s gun violence crisis,” she said in a statement. The NRA called it “shameful,” and predicted consumer revolt. “Lines at Walmart will soon be replaced by lines at other retailers who are more supportive of America’s fundamental freedoms.”

When Forever 21 failed to secure Ariana Grande as its new star endorser ahead of her latest album release, the retailer switched to a nefarious plan B, Ms. Grande alleges in a new $10 million lawsuit against the retail chain.

Forever 21 not only found a Grande lookalike to use instead, according to the lawsuit, but dressed her in Grande-esque hair accessories, put her in a Grande-esque pose, and showed her near a big neon “7” just like the “7 Rings” logo in the video for her song of the same name.

It also accompanied her posts with audio from “7 Rings” and put “7 Rings” lyrics in the captions (“Gee thanks, just bought it”), per the complaint.

The Hollywood Reporter notes that this isn’t new ground for Forever 21 or for celebrities, citing the case of Kim Kardashian vs. Old Navy (eventually settled).

Activision Blizzard’s Overwatch League, in which gamers play “Overwatch” over a season modeled on traditional pro sports, adopted a measure from TV to make it easier for advertisers to consider.

The league averaged 313,000 global viewers a minute across its regular season this year, according to Nielsen data, up 18% year over year.

It’s not an NFL-sized audience by any stretch, CMO Today’s Sahil Patel reports, but Activision Blizzard hopes it’s at least described in a way buyers can use for planning and pricing.

“There were these old-school digital vanity metrics like unique viewers and peak concurrent viewers that the esports industry has been using for a long time to brag about reach—but those numbers don’t mean anything if you can’t make an apples-to-apples comparison with other programming that we are trying to compete with,” says the commissioner of the Overwatch League.

I missed this over the weekend: If you observed Taco Tuesdays yesterday, you may have enjoyed one of the waning days before the popular term belongs to LeBron James.

Basketball’s (possible) Greatest of All Time filed a trademark application for “Taco Tuesday,” which under his ownership would become the name for a whole range of possible businesses, ESPN reports: videos, podcasts, marketing, blogging and a website about sports, entertainment, current events and pop culture.

Seems like a bit of a land grab, but team LeBron tells ESPN’s Brian Windhorst that the filing is mostly about keeping options open. Should we all just try to trademark everything and see what sticks?
