SOCIAL & INFLUENCERS

Diamonds are forever

A few months ago, the USTA faced widespread backlash because of the influx of influencers at this year’s US Open.

That didn’t stop Major League Baseball from doubling down on content creators during its postseason.

MLB is inviting more influencers to ballparks than ever before. More than 200 influencers will attend postseason games this year, and the content generated by them is expected to generate more than 100 million views from their content, according to the league.

Influencers, and certain media partners, also have “access above and beyond just going to a game,” Cameron Gidari, VP of social media and innovation, told Marketing Brew—but to avoid blinding anyone with a ring light, there have been a few stipulations.

“They don’t want to break the rules…so let’s make sure that they’re informed ahead of time,” he said. “Let’s make sure they know what the guardrails are, and we have found that just by doing that, we feel really comfortable about who we’re bringing. A lot of that comes down to the vetting ahead of time…You do the prep ahead of time so that you can have the confidence that it will work out, and it’s less scary in the moment.”

The league’s postseason approach is reflective of a broader revamping of its social and influencer strategy that started around this time last year. Coupled with other initiatives like partnering with popular book, movie, and television franchises, it stands to extend MLB’s fandom to audiences who’ve not previously considered the sport—and deepen the engagement of existing fans during a World Series that features two small-market teams.

The holiday gift list gets a reality check

Sponsor: Reddit For Business

Holiday shoppers are doing their homework. In a Reddit x EMARKETER survey, nearly half said they spend more time researching purchases than they did two years ago. They compare search, retailer reviews, creators, and AI answers, then look for agreement before buying.

Candor helps seal the deal. In the same survey, the majority said they trust a Reddit thread more when it includes both positive and negative opinions, and more than a quarter said an honest take on a product’s downsides helped them feel confident about holiday purchases.

For marketers, confidence takes more than an endorsement; it takes real conversation.

Hit the pavement

If you live (almost) anywhere in New York City, you’ll be hard-pressed to go about your day as usual on Sunday. That’s because the TCS New York City Marathon will, for the 50th time, take over streets spanning all five boroughs.

Ordinarily, closed streets and crowded subway cars mean a whole lot of angry New Yorkers. But on marathon Sunday, the vibe is anything but hostile.

“It is officially and unofficially the best day in New York,” Juliette Morris, chief marketing and digital officer of New York Road Runners (NYRR), the nonprofit behind the marathon, told Marketing Brew. “It’s the only time that people could care less that they can’t cross the street or drive their car. People are so invested in it and the spirit the race brings to the city…We want people out there.”

To be sure that cheering reaches maximum volume over the weekend, NYRR has been running a marketing campaign not only to drive awareness for this year’s marathon but also to promote subsequent NYRR races and running in general. And naturally, out-of-home activations account for a significant chunk of NYRR’s 2026 marathon marketing, including double-decker branded buses, street pole banners, subway ads, digital taxi-top ads, and other digital OOH signage.

“It’s to get the message to New Yorkers where they are every day—commuting, walking on the streets—and…to create that excitement, that tune-in, that spectator activity,” Morris said.

For more on the thinking behind the campaign and how NYRR is hoping to supercharge this upcoming marathon weekend into broader interest in the organization’s efforts, read more here.—AM

Not buying it

After a year and a half of “51st state” taunts from President Trump, escalating tariffs, and most recently, outright import bans, it may come as no surprise that many Canadians are snubbing American products.

  • More than half (51%) of Canadians avoid buying US-made products when possible, according to a new report from Abacus Data based on a September survey.
  • That’s up from 38% who’d avoided American products when Abacus asked in February 2025 amid Trump’s initial tariff threats against Canada.

Seven in 10 Canadians want grocery stores to remove American products from shelves. Even more want them to stock more Canadian and other non-US alternatives (87%) and to clearly label products that are made in Canada (89%).—AAN

Stat: $1.5 billion. That’s how much Anthropic could spend on advertising this year as it prepares for an IPO, according to an analysis of the company’s S-1 filing from the newsletter Madison and Wall and cited by Ad Age.

Quote: “I don’t think The Odyssey made a billion dollars at the box office because people were craving an ancient Greek text to be adapted. I don’t think it was entirely because of the stars, either. I think it was that Christopher Nolan has built a brand, and people are buying tickets a year in advance for one of his movies to spend three hours in his mind.”—Kishori Rajan, producer and writer at Viva Maude, speaking to Bloomberg about the importance of human authorship and AI’s impact in the creative and production industry
