A Brief History of Customer Support and What the Future Holds

Customer support is one of humanity’s oldest business rituals. It predates modern commerce and remains central to brand-consumer relationships.

In ancient marketplaces, reputation was everything. Merchants met buyers, resolved complaints instantly, and built loyalty through trust and quick responses. During the digital boom, support became a maze of call centers, clunky software, and ineffective chatbots.

Today, support is at a breaking point. It feels more complex, costly, and paradoxically less human. But this isn’t the end, it’s a signal. We’re at a turning point. The next evolution of customer service won’t come from another script or helpdesk software, but something fundamentally different.

To understand how we arrived at this crossroads, it's helpful to look back at the origins of customer support—a journey that reveals how each era set the stage for the next.

The Origins Of Customer Support

Customer support isn’t a modern invention - it has existed as long as commerce. The oldest written complaint dates back nearly 4,000 years to Mesopotamia.

Around 1750 BC, a copper merchant named Ea‑nāṣir was called out by a furious customer named Nanni. In an age with no customer service hotlines or chat windows, Nanni used what was available: a clay tablet.

Nanni prepaid for copper, but discovered the metal was substandard and not what he paid for. When his messenger tried to return it, Ea‑nāṣir refused and insulted the messenger. So Nanni did what any determined Bronze Age buyer would: he filed a formal complaint by carving it into a clay tablet.

We’ll never know if Ea-nāṣir made amends. But Nanni’s words survive now, housed in the British Museum. His message endures: fairness, quality, and respect matter. When wronged, customers find ways to make themselves heard—even if it requires carving their message in stone.

From Trust to Scale: Early Support as Business Grows

For centuries after Nanni’s complaint, customer support was personal and local. One bad interaction could ruin a market stall or a family name.

As trade routes expanded, merchants entered new regions using agents and intermediaries. Buyers and sellers no longer met directly. Transactions spanned distances, creating delays, disputes, and friction.

Businesses responded the only way they could: by creating rules. Guarantees, refund policies, and return processes emerged not from generosity but from necessity. Some even printed promises on packaging, turning reliability into a selling point.

In the early 19th century, the first department stores opened. Around that time, U.S. retailer John Wanamaker famously introduced the “money-back guarantee”. His policy helped build trust at scale. Support transformed from a local promise into a business strategy. These changes started a transformation. Support shifted from handshake deals to an operational business layer.

By the early 20th century, support formalized quickly. Departments appeared, and roles became defined. Handling complaints became a specific job, not just everyone’s duty. Customer support left the market stall for the corporate structure. Its next leap would come with wires, circuits, and switchboards.

The Telephone Era

When Alexander Graham Bell first spoke into a device in 1876, he couldn’t have foreseen its future impact. His invention became the backbone of global customer support. With voice traveling over wires, businesses gained a transformative ability: serving customers remotely and in real time.

In those early decades, calls were answered by switchboard operators. Among them was Emma Nutt, who in 1878 became the first female telephone operator. Hired for her calm voice and professionalism, she replaced impatient boys and quickly set the standard: empathy, clarity, and tone mattered. Her role marked one of the first times service became something you heard, not just received.

Call Centers Emerge

As telephony matured, businesses saw opportunity. By the 1950s, they began building centralized call centers. The first one was Birmingham Press & Mail in the U.K., which installed a PABX (Private Automatic Branch Exchange) system to handle rising inquiry volumes. Rows of agents worked phones together, marking a new phase of scalable support.

The next leap came in the 70s with Automatic Call Distributors (ACDs). This technology could route incoming calls based on queues, skills, or availability. With basic customer records, agents responded faster and more consistently.

This era introduced a new logic to support:

• Speed and scale: No longer limited by geography, businesses could serve customers worldwide.
• Data-driven performance: Metrics like handle time, wait time, and resolution rate became KPIs.
• Functional specialization: Dedicated teams for billing, tech support, and retention emerged.
• Toll-free numbers: 1-800 lines eliminated the cost barrier for customers, expanding access.

Despite advancements, the telephone era presented persistent challenges. Agents often lacked complete customer context, systems remained siloed, and call spikes strained resources. While technology improved call management, support continued to rely on human labor and reactivity. Nonetheless, this period established core foundations: centralized operations, routing logic, and performance systems, setting the stage for digital support and multichannel experiences.

Digitalization Era

By the late 1990s, as the internet went mainstream, customer support quietly moved from call centers to keyboards. Suddenly, customers didn’t have to wait on hold or call during business hours; they could write an email anytime, hit send, and expect a reply.

Emails & Early Helpdesks

Email became the first truly asynchronous support channel. For businesses, it was cheaper, more efficient, trackable, and scalable. For customers, it offered convenience. But there were tradeoffs: longer wait times, fragmented conversation threads, and templated replies that often felt impersonal.

To manage rising volume, companies adopted early helpdesk software and ticketing systems. These tools transformed messages into support ‘tickets’ with unique IDs. Tickets could be tracked, queued, categorized, and assigned to agents based on priority or expertise. This brought order to the inbox but also caused a shift in tone. Conversations became case numbers. Customers became queue items.

CRMs

To restore some of that lost context, companies began implementing Customer Relationship Management (CRM) systems. Early tools like TeleMagic (launched in 1985) helped businesses store customer data, track interactions, and centralize communication.

By the late 1990s, cloud-based CRMs like Salesforce brought scalability and integration across sales, marketing, and service teams. At their best, CRMs enabled fast, personalized resolutions. At their worst, they became clunky databases that agents found difficult to use.

This digital stack (email, ticketing, helpdesks, CRM) marked a turning point. Support became more structured, measurable, and scalable. Still, key limitations remained. Customers still had to start the conversation. Agents still searched siloed systems. Many interactions felt transactional, not human. Automation was basic: macros, canned replies, and routing rules lacked true intelligence.

The Multichannel Explosion and the Age of Expectations

As smartphones, social media, and messaging apps became daily tools, support spread across all of them. Suddenly, businesses did more than reply to emails. They handled complaints on Twitter, managed refunds in Facebook DMs, and answered questions on WhatsApp and SMS. Support was now real-time, multi-platform, and public.

A single tweet could trigger a PR crisis. A helpful reply might go viral as a screenshot. Customers expected brands to respond in their channels, on their terms. They also demanded consistency. Support was no longer private; it was a performance.

Amazon, for example, operates a dedicated Twitter support account @AmazonHelp, which replies to customers in multiple languages, adds human initials to responses, and engages publicly before continuing in private threads.

To manage this, new tools appeared. Platforms such as Zendesk and Intercom added social integrations. Dedicated social support teams followed. But something deeper changed. Customer experience (CX) moved from a back-end function to a front-line differentiator.

Speed, tone, personalization, and resolution became brand signals. Support was not just about fixing problems; it now shaped perception. Omnichannel, real-time service needed large, distributed teams. Even then, it stretched capacity.

In that high-pressure context, chatbots entered the scene. And they came with big promises.

Chatbots

By the early 2010s, websites, social media, and mobile apps became gateways to customer experience. A new solution arrived: chatbots. Fast, scalable, and available 24/7, they promised to ease support team workloads and give customers instant answers, all without humans.

Initially, it seemed the future of support had arrived. Businesses enjoyed cost savings and customers received rapid replies. Early interfaces, often on websites or messaging apps, created the illusion of conversation.

As chatbots spread, problems appeared. Bots misunderstood users and repeated irrelevant steps. They missed nuance, emotion, and context. Many became digital gatekeepers, blocking access to humans instead of helping.

When the Illusion Broke: Why Bots Disappointed

In 2023, a widely shared incident involved DPD’s chatbot in the UK. When pushed by a user, the bot began swearing, criticizing its own company, and even composing poems about its uselessness. It was quickly taken offline.

Meanwhile, regulators started raising concerns: the U.S. Consumer Financial Protection Bureau warned that financial institutions were using chatbots that misled or frustrated customers with limited functionality and no clear escalation paths.

Security and privacy concerns followed. Researchers analyzing chatbots on the top 1 million websites found widespread issues: insecure communications, poor encryption, and tracking cookies embedded in chatbot iframes, raising alarms for anyone using bots to handle sensitive data.

More fundamentally, users simply didn’t enjoy the experience. Surveys consistently show that people prefer human agents for anything beyond the basics. Complex queries, emotional tone, and one-off scenarios tend to break chatbot logic. And when bots fail, they don’t just disappoint - they frustrate.

Beyond the Bot: What Comes Next

The rise of generative AI and large language models brought a new kind of promise - bots that could understand intent, handle nuance, and learn from interaction. But traditional chatbots weren’t built for that. They relied on static flows and keyword matching, not real intelligence.

So the dream of fully automated support lived on, but the tools had to evolve. The industry began looking beyond bots to something more capable. Something that could act, adapt, and scale like a team, without pretending to be human.

AI Agents

Customer support today is under pressure from all sides. Expectations are high, volumes are rising, and the systems built over the last two decades are starting to crack. What used to be considered modern technology now feels bloated, fragmented, and increasingly out of step with how customers behave and what they expect.

But pressure creates movement. And today, that movement is AI agents.

New Era Of Customer Support

Not bots, not scripts, and not just another tool layered into the stack, but a new kind of digital worker, designed to operate inside systems, follow procedures, and complete tasks end to end. Unlike chatbots that simulate conversation, AI agents resolve real cases. Processing returns, updating accounts, verifying details, escalating when necessary, all without stepping outside predefined rules.

The difference isn’t just in the experience. It’s in the architecture. These agents aren’t trained to guess. They’re built to act. And they do it 24/7, across every channel, without relying on templates, decision trees, or keyword matching. They’re structured to follow business processes, stay within guardrails, and escalate only when human judgment is required.

The shift is already happening. According to KPMG’s GenAI Pulse Survey (Q3 2025), the number of organizations deploying AI agents has nearly quadrupled in just two quarters, from 11% to 42%. And it’s not just adoption that’s shifting: 76% of leaders now expect employees to manage AI agents as part of their workflows within 2-3 years.

Why Now?

Because both math and technology have changed.  Teams can no longer scale linearly with demand. Hiring more agents doesn’t solve systemic overload. But redistributing work does. The recent breakthroughs in large language models and multi-agent systems have finally made it possible to build digital workers that can reason, act, and operate inside real business workflows: safely, contextually, and at scale.

Support teams are starting to redistribute work, allowing AI agents to handle repetitive, time-sensitive, high-volume tasks, while human agents focus on what they do best: solving complex issues, improving systems, and guiding strategy. It’s not automation for its own sake. It’s an operational change - driven by necessity.

For years, support has been scaled by adding more people. Now, it’s scaling by adding capability. And companies that adopt early are already seeing results: Eneba (one of the fastest-growing gaming marketplaces worldwide), for example, has cut customer support costs by over 60% with AI agents handling the front lines, freeing their team to focus on higher-value work.

“This is not just cost savings, it’s a foundation for scaling without proportional hiring and growing seamlessly across every channel, from email to chat to voice. Ace Waves AI is now part of our core CX strategy” - says Šarūnas Dubauskas, VP of Finance at Eneba

This isn’t a future scenario. It’s happening now. And it’s reshaping how businesses think about scale, service, and success in real time.

Wrapping it up

Customer support has always been a mirror of its time. From Nanni’s clay tablet to call centers, from ticketing systems to bots, every leap forward reflected a shift in how businesses operated and what customers expected. But for all the innovation, many of the same frustrations persisted: long waits, rising costs, generic replies, disconnected systems.

Now, something different is happening. Not just an evolution in tools, but a change in the very fabric of how support gets done. AI agents aren’t just responding to tickets faster. They’re rethinking who, or what, does the work.

For companies, this shift isn’t optional - it’s existential. As volumes rise and budgets tighten, those who embrace the new model will gain speed, scale, and focus. Those who don’t may find themselves stuck in a system built for a different era, while competitors move on.
