Marketing Technology Terminology Summarized: A Guide to Advertising Technology Vocabulary
Published on Jul 23, 2025, at 04:23 PM IST
The digital advertising landscape has undergone a remarkable transformation, rooted in the transition from traditional advertising to programmatic advertising. This transformation, driven by advancements in internet and computing technology, has given birth to the Advertising Technology (AdTech) ecosystem.
Origins and Early Developments
The 1990s marked the beginning of digital advertising, with basic banner ads and email marketing serving as the foundation. As the internet grew, advertisers sought more precise targeting and measurability compared to traditional media. Enter the Ad Server, software developed to manage, deliver, and track online ads served across various websites.
Programmatic Advertising and Real-Time Bidding (RTB)
The mid to late 2000s saw the emergence of programmatic advertising, automating the buying and selling of ad inventory. Real-Time Bidding (RTB), introduced around 2007-2010, revolutionized the industry by enabling advertisers to bid in real time for each impression on ad exchanges, dramatically increasing efficiency and targeting capabilities.
Demand-Side Platforms (DSPs) and Supply-Side Platforms (SSPs)
DSPs and SSPs, developed as counterparts post-RTB, have played a pivotal role in the AdTech ecosystem. DSPs, such as Demand-Side Platforms, allow advertisers or agencies to purchase ad impressions automatically across multiple exchanges and publishers, guided by targeting and optimization criteria. On the publisher side, SSPs, like Supply-Side Platforms, help publishers manage and sell their inventory programmatically by connecting to multiple ad exchanges and DSPs to maximize yield.
Evolution Highlights
From early forms of digital ads in video games to the complex, automated marketplace we know today, the AdTech evolution has been marked by significant milestones. The rise of smartphones and mobile gaming in the late 2000s and 2010s accelerated programmatic ad formats, enabling interactive, targeted, and video ads driven by user data and real-time bidding. Advances in AI and data analytics further enhanced targeting, automation, and personalization in AdTech ecosystems.

This digital ad ecosystem has transformed from rudimentary banner ads delivered via ad servers to a complex, automated marketplace where machine learning and real-time data drive advertising effectiveness. While early forms of online and in-game advertising provided a foundation, it was the development of DSP/SSP technologies and RTB that revolutionized how ads are bought and sold, providing better targeting, yield, and measurement.
