History – 1
Before exploring the future, I began by asking the AIs (Claude, ChatGPT, DeepSeek) to write a history of marketing and advertising agencies.
The Earliest Agencies: Space Brokers to Brand Architects (1840s-1950s)
The origins of marketing agencies were remarkably humble. In 1841, Volney B. Palmer established what many consider the first advertising agency in Philadelphia, operating primarily as a “space broker” – purchasing newspaper advertising space wholesale and reselling it to businesses at a markup. This transactional model dominated the industry’s infancy.
By the late 19th century, agencies began their first significant evolution. J. Walter Thompson (founded 1864) pioneered the transition from mere space selling to offering creative services and strategic guidance. Similarly, McCann Erickson (established 1902) began developing comprehensive brand messaging as America industrialised. During this period, most businesses operated under the simple belief that good, affordable products would naturally attract customers, with marketing limited to basic product announcements.
The 1920s-1940s marked what historians call the “Sales Era,” as intensified competition forced consumer goods companies to develop more sophisticated selling techniques. Agencies formalised their structures to meet these needs, though their focus remained largely on persuasive tactics rather than deep customer understanding.
It wasn’t until the post-WWII economic boom that agencies truly came into their own as creative powerhouses – the era immortalised in “Mad Men.” This period saw marketing departments gain substantial influence over company direction, with agencies as their partners in crafting national brand identities. Creativity and mass media buying dominated the agency model, with legendary figures like Bill Bernbach, David Ogilvy, and Leo Burnett establishing agencies that would define advertising for decades.
The agency model was straightforward: 15% media commission plus production fees, with services divided into account management, creative development, media purchasing, and production. Measurement remained largely rudimentary – often guesswork – with agencies competing primarily on creative flair and storytelling ability rather than quantifiable results.
The Marketing Company Era and Agency Transformation (1960s-1990s)
The 1960s-1990s saw marketing agencies expand their influence as businesses increasingly prioritised customer satisfaction over pure product focus. This period witnessed the emergence of Direct Marketing and early Customer Relationship Management (CRM), utilising databases for more targeted campaigns.
Yet this era also cemented a problematic division within marketing operations: acquisition teams commanded 80-90% of budgets pursuing new customers through media buying and campaign management, while CRM teams operated as smaller, often marginalised units focused on retaining existing customers through loyalty programs, email, and personalised communications.
Agencies mirrored this division, with traditional agencies handling mass brand messaging and specialised direct marketing agencies managing customer retention – creating disconnects that would have lasting consequences for marketing efficiency.
The Age of Consolidation: Global Giants Emerge (1980s-1990s)
The 1980s witnessed perhaps the most significant structural transformation in the agency landscape with the rise of holding companies. This consolidation was epitomised by WPP – originally Wire and Plastic Products, a manufacturer of shopping baskets – which Martin Sorrell transformed through aggressive acquisitions into the world’s largest marketing services company.
Similar holding companies emerged: Omnicom (formed in 1986 through the merger of BBDO, DDB, and Needham Harper), Interpublic Group, Publicis, and Japan’s Dentsu. These conglomerates swallowed independent agencies to form massive marketing networks that could serve global clients across multiple disciplines and regions.
The holding company model was driven by several converging forces:
- Client globalisation demanding worldwide agency presence
- Media fragmentation requiring broader expertise
- Financial pressures for economies of scale
- The need to offer integrated services beyond traditional advertising
This consolidation created “full-service” offerings through specialised agencies under single corporate umbrellas. A client might simultaneously work with several agencies within the same holding company – one for creative development, another for media planning, yet another for PR or direct marketing.
While this model delivered shareholder value through acquisition and cross-selling, it often created complexity that clients found challenging to navigate. Critics argued that consolidation stifled creativity and entrepreneurial spirit, setting the stage for boutique agencies to emerge as nimble alternatives.
Relationship Marketing Era (1990s-2010)
The 1990s and early 2000s saw agencies emphasising the creation and maintenance of long-term customer relationships. However, the fundamental division between acquisition and retention persisted and even deepened. Acquisition continued to dominate agency budgets and attention, with retention activities receiving proportionally less investment despite their proven ROI advantage.
Boutique agencies found new purpose during this period, specialising in emerging disciplines like customer experience design, loyalty program management, and early digital marketing. Agencies like Crispin Porter + Bogusky gained recognition for edgy campaigns that larger, more process-driven competitors struggled to match.
