The Rise of First-Party Data: A History Since 1994

First-party data feels like a recent concept because the term itself only became common marketing vocabulary in the last several years, but the practice it describes, a business collecting and using information customers give it directly, is much older than the phrase.

The cookie that made all of this necessary

The story of first-party data is inseparable from the story of the cookie, which Netscape engineer Lou Montulli created in 1994 to solve a simple problem: the web had no memory, and an online shopping cart needed to remember what was in it between page loads. That original use was, by definition, first-party: a site remembering its own visitor. It didn’t take long for the same mechanism to be repurposed by ad networks to track people across sites they didn’t directly visit, which is the third-party use that eventually drew regulatory and browser-level restrictions decades later. The distinction between first-party and third-party cookies everyone talks about today was baked into the technology from its first use case.

CRM and the discipline of owning the relationship

Parallel to the cookie’s evolution, businesses were building the discipline of managing customer relationships directly. Customer relationship management software, with Siebel Systems as an early major vendor founded in 1993, gave sales and service teams a structured way to hold what they knew about a customer and act on it. This wasn’t originally a marketing tool, but it established the principle that owning a direct, structured record of a customer relationship was worth building software around, which first-party data strategy later inherited wholesale.

Permission marketing named the philosophy

In 1999, Seth Godin published Permission Marketing, arguing that marketing aimed at people who had explicitly agreed to receive it would outperform marketing that interrupted people who hadn’t. The book predates the CDP, the cookie ban and most of the technology this entire topic runs on now, but its central argument, that data and attention given willingly are worth more than data and attention taken by force, is essentially the philosophical foundation first-party data strategy operates on today, even when nobody involved has read the book.

Regulation forced the issue

GDPR took effect across the European Union in 2018, requiring explicit consent for a lot of data collection that had previously happened by default. California’s CCPA followed, effective January 1, 2020. Both laws were aimed at third-party tracking and data brokering more than at first-party relationships, but their practical effect was to make third-party data meaningfully riskier and more expensive to use, which made the case for first-party data stronger by comparison even before the browsers acted.

The announcement that turned a trend into an emergency

On January 14, 2020, Google announced it would phase out third-party cookie support in Chrome within two years. Safari and Firefox had already restricted third-party cookies, but Chrome’s dominant market share meant this was the announcement that made the shift unavoidable for the entire industry, not just for businesses that happened to rely heavily on Safari traffic. What had been a multi-decade slow drift, from the cookie’s original first-party purpose, through CRM, through permission marketing, through GDPR, arrived at a hard deadline almost everyone had to plan around.

The through-line

Every step in this history points the same direction: value that a business earns directly from a customer it has an honest relationship with turns out to be more durable than value borrowed from tracking infrastructure it doesn’t control. That’s not a new insight in 2020. It’s the oldest idea in this whole story, just finally forced to the center of the industry by circumstances outside any individual marketer’s control.
