(Press-News.org) New INFORMS Marketing Science Study Key Takeaways:
YouTube influencers increase player engagement and playtime but often reduce game purchases, especially for story-driven games.
A unique event in YouTube’s history, the “Adpocalypse,” allowed researchers to measure the causal impact of influencer content, revealing its complex effects on game sales and usage.
Game developers must align their business models with influencer marketing, because games with in-game purchases benefit from exposure, while single purchase games may lose revenue.
BALTIMORE, MD, March 14, 2025 – YouTube influencers are shaping the gaming industry in unexpected ways, and a new study in the INFORMS journal Marketing Science uncovers the surprising truth: Although influencers can drive massive engagement with video games, they might also be costing game developers millions in lost sales.
The study, “Opposing Influences of YouTube Influencers: Purchase and Usage Effects in the Video Game Industry,” provides the first causal evidence of how influencer marketing affects gaming. Researchers found that although YouTube gaming content increases playtime, it may also discourage purchases – particularly for narrative-driven games in which viewers can experience the full storyline by watching playthroughs.
More Views, More Playtime – But Fewer Sales?
Using extensive data from Steam, the world’s largest PC gaming platform, the researchers uncovered a double-edged sword: YouTube influencers drive more engagement with the YouTube influencers and longer playtime, but their content can actually hurt game sales.
“YouTube gaming content is a blessing and a curse,” says Nan Li, the study’s lead author and professor at Tongji University. “It can turn a game into a viral sensation, but for some games, especially story-driven ones, people may choose to watch instead of buy. That’s a major challenge for developers.”
The “Adpocalypse” Effect: A Game-Changer for Research
The researchers took advantage of a unique event in YouTube’s history – known as the Adpocalypse – in which a sudden change in YouTube’s advertising policies forced influencers to delay their uploads. This gave researchers a rare opportunity to study the causal impact of influencer content, free from the usual biases.
“Most influencer studies can’t separate cause and effect,” says Avery Haviv, a professor in the Simon Business School, University of Rochester. “But this moment in YouTube’s history gave us a natural experiment to measure the real impact of gaming videos on sales and engagement. The results were eye-opening.”
What This Means for the Gaming Industry
The findings explain why companies have been divided on influencer marketing. Although games that rely on long-term engagement (like Minecraft or Fortnite) benefit from YouTube’s reach, single purchase games (e.g., story-driven RPGs) may actually lose revenue when influencers share full playthroughs.
“It’s clear that one-size-fits-all marketing no longer works in gaming,” says Li. “For games that make money from in-game purchases, influencer exposure is free advertising. But for single-purchase games, developers must think twice about their strategies.”
The Bottom Line: Friend or Foe?
With YouTube gaming content making up one-third of all YouTube traffic, and gaming influencers driving billions of views, this research delivers a critical message: influencer marketing is powerful, but it’s not always profitable. “For game developers, the question isn’t whether influencers matter – it’s whether they help or hurt the bottom line,” says Mitch Lovett, a professor in the Simon Business School, University of Rochester. “The answer depends entirely on the business model.”

A team of researchers from the University of Ottawa has made significant strides in understanding the ionization of atoms and molecules, a fundamental process in physics that has implications for various fields including x-ray generation and plasma physics.
Think about atoms - the building blocks of everything around us. Sometimes, they lose their electrons and become charged particles (that's ionization). It happens in lightning, in plasma TVs, and even in the northern lights. Until now, scientists thought they could only control this process in limited ways.

We’ve mapped nearly all of Mars’ surface from orbit, yet we know less about Earth’s ocean floor — almost 75% remains unmapped in high resolution.
This terrestrial blind spot is driving NJIT Mathematics Professor Eliza Michalopoulou’s latest research, funded by the Office of Naval Research (ONR). The project aims to improve how scientists explore the vast, uncharted ocean floor through sound.
“Mapping the seabed is a challenging endeavor due to the extreme conditions,” said Michalopoulou, ...
Following the 3,000th orbit of NASA’s AWE (Atmospheric Waves Experiment) aboard the International Space Station, researchers publicly released the mission’s first trove of scientific data, crucial to investigate how and why subtle changes in Earth’s atmosphere cause disturbances, as well as how these atmospheric disturbances impact technological systems on the ground and in space.
“We’ve released the first 3,000 orbits of data collected by the AWE instrument in space and transmitted back to Earth,” said Ludger Scherliess, principal investigator for the mission and physics professor at Utah State University. “This is a view of atmospheric ...
Life may not have begun with a dramatic lightning strike into the ocean but from many smaller “microlightning” exchanges among water droplets from crashing waterfalls or breaking waves.
New research from Stanford University shows that water sprayed into a mixture of gases thought to be present in Earth’s early atmosphere can lead to the formation of organic molecules with carbon-nitrogen bonds, including uracil, one of the components of DNA and RNA.
The study, published in the journal Science Advances, adds evidence – and a new angle – to the much-disputed Miller-Urey ...

The smoke from fires that blaze through the wildland-urban interface (WUI) has far greater health impacts than smoke from wildfires in remote areas, new research finds.
The study, published this week in Science Advances, estimates that emissions from WUI fires are proportionately about three times more likely to lead ...
Osaka-Japan - We all know someone who seems to defy aging—people who look younger than their peers despite being the same age. What’s their secret? Scientists at Osaka University (Japan) may have found a way to quantify this difference. By incorporating hormone (steroid) metabolism pathways into an AI-driven model, they have developed a new system to estimate a person’s biological age a measure of how well their body has aged, rather than just counting the years since birth.
Using just five drops of ...
UNIVERSITY PARK, Pa. — Proteins are long molecules that must fold into complex three-dimensional structures to perform their cellular functions. This folding process occasionally goes awry, resulting in misfolded proteins that, if not corrected, can potentially lead to disease. Now, a new study has described a potential mechanism that could help explain why some proteins refold in a different pattern than expected. The researchers, led by chemists at Penn State, found that a type of misfolding, in which the ...
PHILADELPHIA – Although the Food and Drug Administration (FDA) located H5N1 bird flu virus in samples of raw, or unpasteurized, milk in tests in four states in April 2024, and bird flu has been detected in commercially sold raw milk, many Americans do not know that consuming raw milk and its products poses greater health risks than consuming pasteurized milk and its products, especially for children. Consuming raw milk can expose one to Salmonella, E. coli, Campylobacter, Cryptosporidium, Listeria, and Brucella – and, potentially, H5N1 bird flu.
A majority of U.S. adults (56%) knows that drinking raw milk from cows, sheep, or goats is less safe than drinking pasteurized milk. ...
MINNEAPOLIS/ST. PAUL (03/14/2025) — A University of Minnesota research team was recently awarded a five-year, $3.8 million grant from the U.S. National Institutes of Health to develop a new cell therapy to combat Alzheimer’s disease. More than 55 million people worldwide live with dementia, which includes Alzheimer's disease and other related conditions.
The project aims to adapt advanced techniques developed for cancer treatment to create specialized macrophages — immune cells that can surround and remove proteins from their environment — to seek out and clear harmful proteins in the brain.
