Samsung wants everyone to know Samsung TV Plus just crossed 100 million monthly active users. It’s a clean, round number. It looks great in a press release. It’s also exactly the kind of metric FAST services lean on when they want to look massive without having to explain how engaged anyone actually is.
The problem isn’t that the number is fake. The problem is that MAU doesn’t tell us anything useful, and worse, it eventually traps companies into defending a metric that has nothing to do with revenue, attention, or long-term value.
I love you, Samsung. I really do. I’m even writing this while my Samsung TV plays in the background. But I hate vanity metrics more, and MAU has been lying to this industry for years. I wrote about it in 2021 for my friends at Stream TV Insider.
If Samsung TV Plus is really firing on all cylinders, the question then isn’t how many people technically touched the app in a 30-day window. The question is why we’re not hearing a peep about total hours watched.
MAU Measures Presence, Not Attention
MAU answers one question: did a device interact with the app at least once this month?
That’s it.
It doesn’t tell you if someone watched for two hours or two seconds. It doesn’t tell you if they came back tomorrow or bounced immediately to another streaming service. It doesn’t tell you whether ads actually ran long enough to matter.
In FAST, that distinction matters more than anywhere else. These services live and die on attention. Advertisers don’t buy “app opens.” They buy minutes, frequency, and consistency. MAU collapses all of that into a binary yes or no, which makes it useless once you move past the headline.
Hardware Distribution’s Doing a Lot of the Work Here
Samsung TV Plus has an advantage most FAST services would kill for. It ships inside the hardware. It sits on the home screen. In many cases, it launches automatically when the TV turns on.
That’s not a secret. If you don’t own a Samsung TV, do a quick Reddit search. You’ll find years of users complaining that Samsung TV Plus turns on by default, hijacks inputs, or pops up when they didn’t ask for it. That behavior absolutely inflates MAU, because every accidental launch still counts as an “active” user.
From a distribution standpoint, that’s smart, maybe. But let’s not confuse default placement with viewer love. One is an OS decision. The other is earned engagement.
MAU Has No Standard, Which Makes It a Mess
Another issue that never gets solved is that there’s no shared definition of what “active” even means.
One FAST service counts a user the moment the app opens. Another might require a stream to start. Another might have a minimum session length. Without a standard, MAU comparisons are meaningless. Everyone’s counting something slightly different, and everyone’s incentivized to count as generously as possible.
It’s the same circular argument the industry keeps having about whether YouTube is TV. Everyone has a take, no one agrees on definitions, and somehow we’re all supposed to pretend the lack of consensus doesn’t matter. That’s fine for panel stages. It’s terrible for measurement.
That’s why MAU works great internally and terribly externally. It’s fine as a directional KPI inside a company. The moment it becomes a marketing headline, it turns into performance theater.
Pluto learned this the hard way. They used to be the biggest MAU touters in FAST. Then, quietly, they stopped talking about it. That was recognition that MAU stopped helping once the business matured and advertisers and shareholders started asking harder questions.
The Multi-Device Problem Nobody Wants to Fix
FAST services have historically benefitted from not forcing authentication. No profiles meant no friction. Viewers could jump in instantly, and services could count every device interaction as growth.
That’s changed, at least partially. Most FAST services now offer authentication. Profiles exist. Cross-device viewing is possible. Favorites and watch history are no longer foreign concepts.
They’re just not required.
That middle ground is intentional, and it’s smart. Optional authentication is ideal for both the business and the consumer. Viewers keep low-friction access. Services preserve reach. But the moment a user authenticates, MAU stops being the growth story.
Once viewing on a TV, phone, and tablet collapses into a single profile, three “users” become one. The data becomes more accurate. The headline number gets smaller. MAU doesn’t measure people. It measures instances, and authentication turns instances into reality.
That’s why MAU actively discourages better product design. Unified profiles, cross-device continuation, favorites, and watch history all improve the experience. They also expose how thin MAU really is. Growth slows. The vanity math breaks. Suddenly, services need a different way to explain momentum.
That’s where viewing hours take over.
Once authentication enters the picture, attention becomes the only metric that matters. Hours watched scale with ad inventory. Hours watched correlate with revenue. Hours watched survive scrutiny.
So MAU sticks around. Not because it’s honest. Not because it’s insightful. But because it postpones the moment when a service has to stop talking about reach and start talking about attention.
If Things Are So Great, Where Are the Hours?
Here’s the part that should raise eyebrows.
Samsung is very happy to tell us MAUs are up. They’ll even say streaming hours grew 25% year over year. What they won’t do is tell us the absolute number of hours watched.
Total viewing time is the metric that actually connects audience behavior to ad inventory. Hours watched equals ads served. Ads served equals revenue. MAU doesn’t map cleanly to any of that.
If Samsung TV Plus is truly one of the most-used streaming services in the world, the hours should be enormous. Big enough to brag about. The silence suggests either the number isn’t as impressive as the MAU headline implies, or Samsung knows hours invite comparisons they’d rather avoid.
MAU Eventually Boxes You In
The long-term problem with MAU is that once you make it the headline, you’re stuck defending it.
Every quarter becomes about hitting a bigger number. That pushes teams toward tactics that juice “activity” without improving engagement. Auto-launch behavior. Aggressive placement. Counting anything that moves as a user.
Meanwhile, advertisers get savvier. Execs start asking why CPMs aren’t scaling with user counts. Agencies want proof of attention, not reach. At that point, MAU stops being an asset and starts being a liability.
That’s why the smartest FAST operators eventually pivot away from it. They don’t abandon measurement. They just stop pretending MAU tells the story.
The Streaming Wars Take
Samsung TV Plus hitting 100 million MAUs isn’t meaningless, but it’s not exactly impressive either.
If Samsung wants the market to believe this service is truly essential viewing, it’s time to stop leading with reach and start leading with attention. MAU tells us how many devices technically touched the app. Viewing hours tell us how much value the service actually creates.
That shift matters because viewing hours do three things MAU never will.
- They translate directly to ad inventory.
- They reflect real consumer behavior, not OS-level placement.
- And they give advertisers something they can model, compare, and buy against with confidence.
MAU was useful when FAST needed to prove it existed. Samsung TV Plus is well past that phase. At this scale, continuing to lead with MAU invites skepticism, not applause. It forces the market to guess whether growth is coming from deeper engagement or simply more hardware in the field.
Viewing hours solve that problem. They reward better product design. They encourage authentication without punishing the headline. They align the narrative with revenue instead of vanity. Most importantly, they signal confidence. Services that lead with hours are telling the market they’re ready to be judged on attention, not just access.
This isn’t the first time we’ve raised questions about how Samsung TV Plus presents its audience metrics.
The Streaming Wars is intentionally ad-free
We don’t run display ads. Not because we can’t, but because we don’t believe in them.
They interrupt the reading experience. They cheapen the work. And they burn advertisers’ money on impressions nobody actually wants.
So we chose a different model.
We say the things people in this industry are already thinking but don’t say out loud. We connect the dots beyond the headline and focus on explaining why things matter to the people working in this business.
