2016 to 2026: what changed in B2B marketing, and what stayed the same 

In 2016, B2B marketing already felt like it was changing quickly. Content marketing was gaining momentum, automation platforms were gaining popularity, and digital channels were reshaping how buyers discovered information. Marketers were building skill sets around channels, tools and execution, and justifying their value through leads, impressions and conversion. 

A decade on, many parts of the operating environment have changed. Buyers are more informed, journeys are more complex, and technology enables unprecedented scale. But the core principles of good marketing, such as clear thinking, strong ideas and strategic judgment, have endured. 

At TSM, we’ve watched marketing practices come and go. What separates lasting impact from fleeting trends is the ability to apply strategies that work regardless of changing environments or new platforms.  

The tools evolve, but the craft lives on.  

1. From channels and automation to connected strategy 

In 2016, B2B marketing revolved around automation and channel execution. Teams were structured around specialist roles: email, paid media, campaign operations, martech. At that time, mastering a channel platform was a genuine source of differentiation. 

In 2026, that is no longer the case. These days automation is assumed, meaning it’s no longer a strategic advantage in and of itself. What clients need now is a system that connects strategy, narrative, data and delivery across functions. Buyers today complete most of their journey before ever engaging sales. In fact, research shows B2B buyers often do 70 per cent of their research before contacting a vendor’s sales team.  

That means marketers must tie together brand, content, demand, sales enablement and experience into a unified growth architecture. Tactical channel activation alone no longer wins. It’s the orchestration across touchpoints that drives meaningful influence. 

TSM Perspective: 

We always say tools without strategy are like engines without a chassis. The world’s best martech stack won’t overcome disconnected thinking. Today, organisational integration and narrative cohesion matter as much as technical execution. 

2. ABM grew up, but the principles never changed 

In 2016, Account-Based Marketing (ABM) was still emerging. Early pilots were often manual, bespoke and driven by intuition and close sales relationships. Teams experimented, but execution was labour-intensive and difficult to scale. 

By 2026, ABM has moved beyond experimentation. According to Demand Gen Report’s 2025 ABM Benchmark Survey, 71 per cent of B2B practitioners report using an account-based marketing strategy, although maturity and execution vary widely. Tools and intent data have improved targeting and orchestration, but the underlying discipline – close sales alignment and deep account insight – remains unchanged. 

TSM Perspective: 

While the execution of ABM has evolved, the fundamentals haven’t changed. It still requires deep sales-marketing alignment, a nuanced understanding of buyer drivers, and tailored engagement at account level. Data and platforms help identify opportunity, but don’t replace strategic discipline. Smart ABM still means cross-functional teams co-creating account plans, agreeing on value hypotheses and aligning on shared metrics. That strategic rigour is what turns insight into influence. 

3. Content became a mainstay, but differentiation got harder 

Ten years ago, content marketing had strengthened its foothold. Companies commonly invested in white papers, blogs and thought leadership pieces that helped educate buyers. There were fewer voices, and that meant originality stood out. 

A decade later, content is ubiquitous. It’s expected rather than exceptional. B2B buyers are interacting with up to seven pieces of content before engaging a sales representative, and some consume even more. Content volume has surged, in part fuelled by AI-assisted production. 

Yet research consistently highlights a paradox: more content has not yielded better differentiation. More organisations produce similar formats and replicate “best practice” structures, making it harder for ideas to break through. 

There is still ROI from content of course, and that return is even higher when paired with solid SEO and GEO and planning. But without distinct positioning, content risks becoming indistinguishable noise is a crowded room.  

TSM Perspective: 

We view content as an expression of strategy. When the strategy is weak, no amount of content can substitute for clarity. When the strategy is strong, the content serves it, not the other way around. More content doesn’t necessarily mean better content, that’s why original thinking matters more than ever.  

4. The funnel has changed, but the idea still matters 

In 2016, marketing funnels were considered linear. Based on the tried and tested buyer sequence of awareness, consideration, and purchase, these funnels were considered relatively standard and relatively safe.  

Ten years on, buying journeys have become far less linear. Research shows that most of the B2B buying journey happens on digital channels before any sales engagement, and many buyers prefer rep-free experiences in the early stages. Buyers self-educate, revisit touchpoints and involve multiple stakeholders asynchronously. 

Despite this complexity, one thing remains true: clarity is what cuts through complexity. A simple, well-organised idea can turn a disjointed journey into a coherent story for buyers, providing guidance when the path is otherwise confusing. 

TSM Perspective: 

We’ve seen funnels evolve and change, but effective campaigns are still anchored in a concise central idea that everyone in the organisation can articulate and reinforce. The journeys are complex, but they still need a simple, strong organising ideas. 

What stayed consistent 

Across decades and disruptions, some fundamentals haven’t changed: 

• Strategy:  good strategic thinking works across sectors, markets and technologies. 

• Trust: buyers still choose vendors they trust. Signals of credibility are paramount. 

• Ideas: a strong idea aligned to buyer insight beats slick tactics any day. 

• Clarity: clarity in messaging, goals and alignment drives repeatable outcomes. 

These themes aren’t buzzwords. They’re enduring truths validated by both data and experience. 

What this means for B2B leaders in 2026 

Today’s leaders must invest in thinking, not just tools. The data shows that buyers are doing their own homework. Here’s what that means for marketers: 

• Meet buyers earlier with clear insights, not just louder messages.  

• Don’t outsource critical thinking to AI, use data to sharpen judgement.  

• Resist trend-chasing that erodes distinctiveness.  

• Build teams that value strategy, craft and collaboration as much as execution. 

In 2026, it’s not about specialists versus generalists. True success lies in integration – connecting insight, ideas, execution and outcomes into a coherent growth architecture.
