Marketing’s understanding of identity has evolved rapidly over the past decade, much like the shifting media landscape itself. From the early days of basic direct mail targeting to today’s complex omnichannel environment, identity has become both more powerful and more fragmented. Each era has brought new tools, challenges, and opportunities, shaping how brands interact with their customers.
We’ve moved from traditional media like mail, newspapers, and linear/network TV, to cable TV, the internet, mobile devices, and apps. Now, multiple streaming platforms dominate, creating a far more complex media landscape. As a result, understanding the customer journey and reaching consumers across these various touchpoints has become increasingly difficult. Managing frequency and ensuring effective communication across channels is now more challenging than ever.
This development has led to a fragmented view of the consumer, making it harder for marketers to ensure that they are reaching the right audience at the right time while also avoiding oversaturation. Marketers must now navigate a fragmented customer journey across multiple channels, each with its own identity signals, to stitch together a cohesive view of the customer.
Let’s break down this evolution, era by era, to understand how identity has progressed—and where it’s headed.
2010-2015: The rise of digital identity – Cookies and MAIDs
Between 2010 and 2015, the digital era fundamentally changed how marketers approached identity. Mobile usage surged during this time, and programmatic advertising emerged as the dominant method for reaching consumers across the internet.
The introduction of cookies and mobile advertising IDs (MAIDs) became the foundation for tracking users across the web and mobile apps. With these identifiers, marketers gained new capabilities to deliver targeted, personalized messages and drive efficiency through programmatic advertising.
This era gave birth to powerful tools for targeting. Marketers could now follow users’ digital footprints, regardless of whether they were browsing on desktop or mobile. This leap in precision allowed brands to optimize spend and performance at scale, but it came with its limitations. Identity was still tied to specific browsers or devices, leaving gaps when users switched platforms. The fragmentation across different devices and the reliance on cookies and MAIDs meant that a seamless, unified view of the customer was still out of reach.
2015-2020: The age of walled gardens
From 2015 to 2020, the identity landscape grew more complex with the rise of walled gardens. Platforms like Facebook, Google, and Amazon created closed ecosystems of first-party data, offering rich, self-declared insights about consumers. These platforms built massive advertising businesses on the strength of their user data, giving marketers unprecedented targeting precision within their environments.
However, the rise of walled gardens also marked the start of new challenges. While these platforms provided detailed identity solutions within their walls, they didn’t communicate with one another. Marketers could target users with pinpoint accuracy inside Facebook or Google, but they couldn’t connect those identities across different ecosystems. This siloed approach to identity left marketers with an incomplete picture of the customer journey, and brands struggled to piece together a cohesive understanding of their audience across platforms.
The promise of detailed targeting was tempered by the fragmentation of the landscape. Marketers were dealing with disparate identity solutions, making it difficult to track users as they moved between these closed environments and the open web.
2020-2025: The multi-ID landscape – CTV, retail media, signal loss, and privacy
By 2020, the identity landscape had splintered further, with the rise of connected TV (CTV) and retail media adding even more complexity to the mix. Consumers now engaged with brands across an increasing number of channels—CTV, mobile, desktop, and even in-store—and each of these channels had its own identifiers and systems for tracking.
Simultaneously, privacy regulations are tightening the rules around data collection and usage. This, coupled with the planned deprecation of third-party cookies and MAIDs has thrown marketers into a state of flux. The tools they had relied on for years were disappearing, and new solutions had yet to fully emerge. The multi-ID landscape was born, where brands had to navigate multiple identity systems across different platforms, devices, and environments.
Retail media networks became another significant player in the identity game. As large retailers like Amazon and Walmart built their own advertising ecosystems, they added yet another layer of first-party data to the mix. While these platforms offer robust insights into consumer behavior, they also operate within their own walled gardens, further fragmenting the identity landscape.
With cookies and MAIDs being phased out, the industry began to experiment with alternatives like first-party data, contextual targeting, and new universal identity solutions. The challenge and opportunity for marketers lies in unifying these fragmented identity signals to create a consistent and actionable view of the customer.
2025: The omnichannel imperative
Looking ahead to 2025 and beyond, the identity landscape will continue to evolve, but the focus remains the same: activating and measuring across an increasingly fragmented and complex media environment. Consumers now expect seamless, personalized experiences across every channel—from CTV to digital to mobile—and marketers need to keep up.
The future of identity lies in interoperability, scale, and availability. Marketers need solutions that can connect the dots across different platforms and devices, allowing them to follow their customers through every stage of the journey. Identity must be actionable in real-time, allowing for personalization and relevance across every touchpoint, so that media can be measurable and attributable.
Brands that succeed in 2025 and beyond will be those that invest in scalable, omnichannel identity solutions. They’ll need to embrace privacy-friendly approaches like first-party data, while also ensuring their systems can adapt to an ever-changing landscape.
Adapting to the future of identity
The evolution of identity has been marked by increasing complexity, but also by growing opportunity. As marketers adapt to a world without third-party cookies and MAIDs, the need for unified identity solutions has never been more urgent. Brands that can navigate the multi-ID landscape will unlock new levels of efficiency and personalization, while those that fail to adapt risk falling behind.
The path forward is clear: invest in identity solutions that bridge the gaps between devices, platforms, and channels, providing a full view of the customer. The future of marketing belongs to those who can manage identity in a fragmented world—and those who can’t will struggle to stay relevant.

African Americans represent 11% of the U.S. adult population and, as a group, constitute the nation’s largest racial minority market. African Americans are also more optimistic about their financial situation than the general population, and with good reason. According to the Selig Center for Economic Growth, African American buying power reached $913 billion in 2008, up from $590 billion in 2000. By 2013, African American buying power will reach an astonishing $1.2 trillion, meaning that almost nine cents out of every dollar spent in the United States will come from African American consumers. In celebration of Black History Month, Experian Simmons examines the attitudes, behaviors and media consumption of our country’s African American consumers using data from Simmons DataStreamSM, the Simmons National Consumer Study, New Media Study, Multi-Media Engagement Study and Experian MicromarketerG3 as well as findings from our friends at Experian Hitwise. When it comes to attitudes towards personal financial outlook, African Americans are more likely than the average American adult to say that in the next 12 months they will be better off financially.

Coffee drinkers in America Coffee plays such an integral part of every day life in America that it may be safe to say that coffee helps the United States go round. In fact, fully 60% of all U.S. households use either whole or ground coffee beans at home. Experian Simmons extensively reviewed the American coffee drinker for this report which features detailed insights into the coffee-drinking American. In addition, we compare the patrons of Dunkin’ Donuts and Starbucks, the leading players in the battle for brew. Coffee in the Home The average U.S. household that uses whole or ground coffee consumes 4.2 cups per day. In total that’s about 280.5 million cups of coffee consumed at home by Americans each day or about 102 billion cups per year. Among households that use coffee, 89% stock regular coffee and 46% stock decaf.* Among households that use coffee, 84% use pre-ground coffee and 26% use whole bean coffee at least some of the time.* Instant Flavored Coffee Over a quarter of households (27%) stock instant coffee. Sixteen percent of households use instant flavored coffee. The most commonly used flavors among instant flavored coffee drinkers are: Older Americans More Likely to Drink Coffee Fifty-seven percent of adults ages 18-24 live in households that use coffee, but 25 to 34 year olds are the least likely to stock coffee in their cupboards with only 54% reporting they use whole or ground bean coffee at home. Coffee Use Increases with Household Income Seventy percent of Americans who report annual household incomes of $150,000+ drink coffee compared with 54% of those with household income less than $25,000.

Two-thirds of U.S. Households Use Coupons Two-thirds of American households (67%) use coupons. And while the vast majority of households using coupons (87%) say they use them to save money, 30% also say that coupons are a way for them to try out new products. Newspapers are still the number one coupon source with 70% of coupon households still getting their coupons from a newspaper. The Internet is growing as a coupon source. A quarter of coupon households get coupons online today, up 46% in the last three years. What Americans Buy With Their coupons Nearly half of all American households use coupons to buy food/grocery products making them the most common items purchased with coupons followed by cleaning products and beauty/grooming products. Seven percent of households buy tobacco using coupons. Where Are Coupons Redeemed? Given that half of U.S. households use coupons for food/grocery products, it’s no surprise that 60% of all households redeem coupons in supermarket, grocery or convenient stores. While only a quarter of all households use coupons at restaurants/fast food chains, that number has risen by 9% since 2006, when 23% of households redeemed coupons at restaurants. Coupons Attract New Consumers With the start of the holiday shopping season around the corner retailers want to make sure consumers visit their store and/or website. One way to drive consumer traffic is with coupons. Close to 50 percent of American adults say they are likely to be drawn to a store they don’t normally shop at by a coupon. The Experian Simmons retail shopping segment known as Mall Maniacs make up just 12% of all shoppers, but that group is 82% more likely to be drawn to a new store by a coupon. Percentage of U.S. Adult Population by Shopping Segment Mall Maniacs and Status Strivers are 66% and 26% more likely, respectively, to appreciate getting emails that announce new products and services. Identifying these consumers is key to maximize online marketing dollars. Additionally, with more and more consumers shopping online, companies should ensure that coupons are redeemable both online and in-stores.
