From Monoculture to Media Fragmentation

There was a time when reaching a large audience was relatively simple.

In the early 1990s, television shows like Cheers and 60 Minutes regularly delivered household ratings above 20. Even as cable began to introduce the first signs of fragmentation, major hits like Seinfeld and Friends could still command enormous audiences.

Today, that kind of shared media experience is increasingly rare.

In 2025, the highest-rated broadcast program outside of mega-events was CBS’s Marshals, which averaged a 2.95 household rating. Compare that with the Super Bowl, which can still bring more than 100 million people together at the same time.

Streaming has created massive audiences of its own, but viewing tends to accumulate over time rather than happen simultaneously. Stranger Things, for example, averaged 32.9 million viewers over a 35-day period, while the 2026 Super Bowl reached 125.6 million viewers across platforms during the single event.

One audience accumulated over weeks. The other showed up at the same time.

The difference illustrates how fundamentally the media landscape has changed. Consumers have more choices than ever about where, how, and what media they consume. We have moved from a world of media monoculture, where a relatively small number of television networks, radio stations, newspapers, and cultural events could reach a significant portion of the population, to one where audiences are spread across an enormous number of platforms and environments.

And that has changed the job of media planning and buying.

The End of “Everyone Is Watching the Same Thing”

A media monoculture made reaching people relatively straightforward.

A buyer could put a meaningful portion of a budget behind a handful of broadcast networks, local television stations, radio formats or major publications and reach a large percentage of the target audience.

Today, consumers divide their attention among streaming services, social platforms, podcasts, creators, gaming, connected TV, YouTube, newsletters, digital publishers, radio and more.

The challenge isn't that there aren't enough places to reach people. There are almost too many.

The job isn't simply to identify where an audience spends time. It is determining which combination of those places will reach the right people without repeatedly reaching the same people.

And finding the right places to reach an audience is only part of the job. Media planners also need to understand how to access the inventory.

The same audience and sometimes even the same inventory can be available through multiple sellers, platforms, publishers, and buying channels. Knowing where and how to buy can make the difference between finding incremental reach and simply purchasing the same audience again.

Without that marketplace expertise, advertisers can duplicate inventory, pay more than necessary, or miss valuable inventory altogether.

Ultimately, all of that complexity comes back to one fundamental objective: reach.

Reach Doesn't Disappear. It Has to Be Built.

One of the biggest misconceptions about today's fragmented media environment is that mass reach is dead. Spoiler, it isn’t.  Headlines five years ago were all about “cord-cutting” which made it sound like consumers were getting rid of TV but in reality they were just changing their access points. 

Audiences haven’t become smaller. Consumers are spending more time across more media than ever. The audience didn't disappear; it dispersed. What has changed is how you reach them all.

Instead of reaching a large percentage of an audience through one or two dominant media properties, planners often have to build that reach across multiple channels, including linear television, CTV, YouTube, digital video, audio, social, search, display, and local media.

Research from Nielsen illustrates the point: campaigns concentrating more than 85% of their spend in a single media bucket reached no more than 17% of their target audience in one analysis, while more diversified campaigns across linear, digital-network, and online-video platforms could reach as much as 90% across CTV, desktop, and mobile.

The implication is important: reach is no longer something you simply buy. It is something you build.

A strong media plan uses different channels to find different portions of the audience, while understanding how those channels work together to maximize unduplicated reach.

The Hidden Problem: Duplication

Fragmentation creates another challenge that isn't always obvious in platform-level reporting: frequency waste.

A consumer might see one ad on CTV, another on YouTube, another while scrolling social media, and another through a publisher's website or podcast. Each individual platform can report strong delivery, but those reports don't necessarily tell you how much the audiences overlap.

Meanwhile, another consumer in the same target audience may not have seen the campaign at all.

This is why a media plan cannot be evaluated channel by channel.

The lowest CPM doesn't necessarily represent the most efficient opportunity. A channel with a slightly higher CPM may provide significantly more incremental reach and ultimately contribute more value to the campaign.

This shifts the mindset from where the cheapest impressions can be purchased to where can we get the most value.  What tactics will allow us to reach the right people? If we add dollars, where can we extend reach not duplicate it?

That requires looking at the media plan as a whole not simply comparing individual channel metrics.

Start With the Audience, Not the Channel

Fragmentation has also changed how we should think about audiences.

In the past, media planning often started with broad demographic definitions: Adults 25–54, Women 25–54, Adults 55+, and so on.

While fragmentation has added complexity to media planning, it has also created an opportunity to target audiences more narrowly. Monoculture made it possible to reach a large audience quickly, but it was difficult to meaningfully segment consumers when the target audience was narrow. Today, the ability to identify and reach more specific audiences creates opportunities for advertisers that simply weren't possible before.

Consider a senior-living campaign.

“Adults 55+” could include an active older adult researching independent living, an adult daughter researching assisted living for her mother, a family facing an immediate memory-care decision, or someone who is years away from making a move.

They are all Adults 55+, but they have completely different needs, behaviors, and media habits.

A strong media plan starts by understanding who we're trying to influence, where they are in the decision journey, and what information they need to move forward.

From there, each media channel can be assigned a job.

• Local television and news may build awareness and credibility.
• CTV and digital video can provide scalable, targeted reach.
• Podcasts or newsletters can connect with specific audiences in trusted environments.
• Targeted digital can capture people actively looking for information.
• Retargeting can help keep the brand in front of people who have already shown interest.

The goal isn't to be everywhere.

The goal is to be in the right places for the right reason.

Context Matters More When There Is No Shared Experience

The end of monoculture has also made the environment surrounding an advertisement more important.

When everyone isn't watching the same television show or reading the same newspaper, the context in which someone encounters a message can help determine how that message is received.

A trusted local news organization, a financial-planning podcast, a caregiving newsletter, a respected health publication or a community event can provide a level of relevance and credibility that a cheap impression cannot.

This doesn't mean every brand needs to pursue niche media.

It means media planning should consider the role of the environment, not just the number of impressions it delivers.

Broad-reach media can provide scale and legitimacy while niche environments can provide relevance. Intent-based channels can capture demand. Retargeting and CRM activation can turn interest into action.

Each can play an important role but each needs a defined job within the overall strategy.

The Media Buy Is No Longer Just About Buying Media

This is perhaps the biggest change of all. Media buying used to be largely about securing access to audiences at the right price. Today, the buyer is managing a much more complicated system and asking questions like:

• Where is the audience under-reached?
• Where is incremental reach available?
• How much frequency is enough?
• Are we reaching the same people across multiple platforms?
• Is a channel actually driving qualified prospects or simply generating inexpensive impressions?

And perhaps most importantly:

What should we change next?

Fragmentation has increased the operational complexity of media, but it has also increased the strategic value of the media planner and buyer. The role is no longer simply about securing inventory. It is about understanding how individual pieces of a media plan work together to produce a business outcome.

The Basics Still Matter

For all the changes in media, some things haven't changed.

Reach still matters.

Frequency still matters.

Creative still matters.

Context still matters.

And a low CPM has never automatically meant an efficient campaign.

The Questions We Ask Have Changed

The old question was often:

“Which program, station, publication or website should we buy?”

The better question is:

“What audience outcome are we trying to create?”

That might be incremental qualified reach, awareness, consideration, an inquiry, a lead, an appointment, a conversion or revenue.

At Avail Media, that means building a media plan around the audience and the outcome, then determining how each part of the media mix can contribute..

The mix will look different for every client because there is no universal media recipe. Television may provide scale. CTV may extend targeted reach. Audio may build repetition and affinity. Retargeting can reconnect with people who have already engaged.

The role of the media planner is to understand how those pieces work together, where they overlap, where they leave gaps, and where the next dollar can create the most value.

That is the opportunity created by fragmentation.

We may no longer be able to reach everyone in one place, but we have more ways than ever to understand an audience, find them in the right environments, and build a media plan around how they actually consume media.

In a fragmented media world, being everywhere isn't the goal.

Being where your audience is and knowing why you're there is.
