Happy 25th Birthday Digital Advertising

The digital advertising industry has evolved exponentially since 1994, the year that the first online banner ad appeared. In this timeline, we will explore the origins of the digital advertising industry and its developments over the past two and a half decades.

  • 1994

    The world's first Banner Ad

    Although the previous year law firm ‘Heller Ehrman White & McAuliffe’ purchased the first online clickable web ad, the first banner ad was in fact purchased by AT&T in 1994.


    The commercial web magazine, HotWired, sold the ad to AT&T for a price of $30,000 with a run time of three months. From then, the term ‘Banner Advertising’ was coined. The ad produced click-through rates of 44% and to put that into perspective, the average click-through rate of a display ad in 2019 is 0.35%.It was around this time that the concept of online advertising really blew up for publishers who were looking for a way to keep their content free.

    The launch of Yahoo!

    Yahoo! was founded by students of Stanford University, Jerry Yang and David Filo, and was developed as a directory of websites organised in a hierarchy.



  • 1995

    Online Display Ads became targeted

    Following the success of AT&T, online display ads became increasingly popular. Advertisers were looking for ways to better target ads, specifically targeting consumer demographics. Ad agency WebConnect, which was the first ad network, began to work with their clients to pinpoint the websites that their ideal consumers visit. Ads were then placed on these websites where by they were more likely to be seen by the most relevant audience. WebConnect also produced a tool to prevent ‘ad fatigue,’ which occurs when users are repeatedly shown the same ad. These developments were revolutionary in the digital advertising space.

  • 1996

    The rise in Ad Servers

    The rise in online display ads meant that advertisers were now looking for ways in which they could measure the results of their efforts. Advertisers needed a system that enabled them to display ads and track their performance to better target internet users. That’s where DoubleClick came in - one of the world’s first ad servers. At this point, it was not owned by Google; the concept had been developed by Kevin O’Connor and Dwight Merriman. DoubleClick was one of the first on the scene to offer ROI tools for ad campaigns, enabling businesses to see if their money was being spent well. The emergence of DoubleClick meant that a new pricing model was introduced by Netscape and Infoseek (search engines) - cost per thousand impressions (CPM).

    IAB was founded

    The Interactive Advertising Bureau (IAB) was also founded in 1996. The IAB was organised as a solution to streamline industry standards, conduct research and provide legal support for the online advertising industry.



  • 1997

    Pop-up Ads & Blockers were developed

    The year that Tripod employee Ethan Zuckerman invented pop-up ads as a way to capture the attention of ad-blind users. Fortunately, they were quickly considered as intrusive and annoying. This then led to pop-up ad blockers being developed and installed, reducing their effectiveness.

  • 1998

    Introduction of the Google search engine

    The web was rapidly expanding and the number of websites was rising by the day. Users needed a way to easily navigate the web and as a result, search engines began to steadily gain popularity. Although other search engines existed, such as AltaVista, Lycos and Infoseek, this year saw the birth of the Google search engine - a player that, to this day, leads the digital advertising industry.

    GoTo.com paved the way for search advertising

    By this time, the click-through rates had begun to drop on display ads. As a result, advertisers began to turn to paid search and Pay-per-click advertising. The Search Engine Goto.com pioneered the keyword auction model with a search engine where the results were determined solely by which listing had the highest bid on a term. Goto.com would later become Overture before morphing into Yahoo search marketing.

    The very first adtech acquisition

    Microsoft pays $265million for LinkExchange, an early form of online advertising network based off the concept of a webring.

  • 1999

    DoubleClick buys NetGravity and Abacus Direct

    In two separate acquisitions, DoubleClick swallows up adserver company NetGravity and market research firm Abacus Direct. The resulting combination of technology, reach and data puts DoubleClick in a strong position to establish dominance in the growing online advertising sector.


  • 2000

    The Dot Com Bubble booms

    The Dot Com Bubble peaked in 2000 as a result of colossal speculative investment in the industry. Many investors were eager to invest after seeing the exponential progress of the internet. Paid search engines, such as Yahoo, paved the way for other powerful online advertising models.

    Birth of Google AdWords

    This year saw the birth of Google AdWords (Now Google Ads), which was developed as a solution to the user experience of paid search that was suffering due to corrupt results. The intent of AdWords was to develop a sponsored search experience that didn’t compromise the quality and relevance of search results. This was achieved through Google’s Quality Score model which is still used today.

  • 2001

    The Dot Com Bubble bursts

    The value of internet-based companies had already began to rapidly decrease towards the end of 2000. This meant that in 2001, the Dot Com Bubble was bursting. Many online shopping companies, such as Amazon, saw an astronomical drop in share prices, whilst others simply failed and shut down. One company that survived and prospered the Dot Com bust was Google. Google took the opportunities that the Dot Com bust had to offer and flourished from it, filling the space that the existing players had left behind.

  • 2002

Google's PPC model differed from others in that users could not buy their way to the top, as Google focused their model around ad relevancy and a better user experience.

  • 2003

    Google acquired AdSense

    Google AdSense came along in 2003, initially operating under the name “Content-Targeted Advertising” - but Google wasn’t alone in this arena. ‘Applied Semantics’ was also competing in the contextual ads sector operating under the AdSense name, until April when Google acquired the company.
