Jif peanut butter unveiled a limited-edition jar labeled “Gif” as part of a clever partnership with GIF repository Giphy. The stunt, created by Publicis’ PSOne agency in New York, reignites a long-running debate about the correct pronunciation of GIF. The special Gif edition of otherwise normal Jif peanut butter—which also has the original label on the opposite side—went on sale via Amazon Monday and promptly sold out in a matter of hours. In addition to the limited-edition label, the campaign also includes a video and a series of branded GIFs that will fuel social media arguments for years to come.

Watch: A totally real professor of “linjuistics” explains why GIF is so obviously pronounced Jif.

• In other GIF news, the world finally has GIFs worthy of Joel Embiid, one of the greatest trash talkers on Twitter. You can thank Mountain Dew for these gems.

Longtime Disney CEO Bob Iger will step down from the helm of the media and entertainment giant but will remain at the company as executive chairman through the end of 2021, the company said today.

When CBS and Viacom announced their plans to merge last August, some in the industry speculated that Jo Ann Ross, who had presided over CBS ad sales since 2002, might take it as an opportunity to retire. Instead, settled into her new corner office high up in ViacomCBS’ Times Square building two and a half months after the merger was completed in December, Ross finds herself busier than ever (“there’s not enough hours in the day!”), juggling meetings with company execs, her expanded ad sales team and clients.

As U.S. officials say the spread of coronavirus in the U.S. appears inevitable (which is leading to a run on medical supplies on Amazon), authorities in China have been working for weeks to contain the outbreak, including such measures as closing businesses and limiting transportation in some areas, which, in turn, has disrupted the nation’s supply chain.

Bernie Sanders at $46 million and former South Bend, Ind., mayor Peter Buttigieg at $33 million.

"Environmentalism is important to us at T3 as not only do we need to take care of our planet, but we also need to take care of our future generation's planet. Our carbon emissions are out of control, and if we look at it as if it's too big of a problem for just one person, or one company to make a difference, nothing will ever change. Many of our employees have approached us with their own efforts, such as using reusable plates and cutlery instead of disposables for our catering events. We even reach out to CPG companies when they have packaging with excessive plastics. Every single effort matters."
