An advertisement has a peculiar double life. To the person reading a website, it is a rectangle to notice or ignore. To the publisher, it is a promise: show this message to these people, this many times, and prove that you did. The rectangle gets the attention. The promise requires machinery. The story of 24/7 Media turns on the difference.
- Sell the space. Build a network connecting websites and advertisers.
- Run the system. Make ad delivery, targeting and measurement useful together.
- Follow the assets. WPP buys the company; Xaxis absorbs it; Open AdStream moves to AppNexus.
The crash came before the code
David J. Moore came from television advertising. In 1995, he co-founded Petry Interactive, a predecessor of the business assembled as 24/7 Media in 1997-1998. The company went public in August 1998. An online advertising network was an appealing proposition: advertisers could reach many websites without negotiating with each one, while publishers gained a sales force they did not have to build themselves.
Then the dot-com market collapsed. In a 2015 interview, Moore recalled a share price that had reached $69 falling to 15 cents in 2001. The collapse made expansion difficult to sustain. That April, the company announced a restructuring eliminating 100 jobs. Businesses were sold, including Exactis and Sabela technology assets. Survival required deciding which capabilities deserved the remaining cash.
Real Media supplied a consequential answer. Acquired in 2001, it brought Open AdStream, a publisher ad server. Moore’s later account identifies that technology as central to the shift from media sales toward a software business. The strategic lesson is less romantic than a founder refusing to quit: the company changed what it could sell.
The unglamorous job worth keeping
Consider a publisher juggling several campaigns. One advertiser wants a particular audience. Another expects a guaranteed number of appearances. The sales team needs to know what remains available, and the operations team needs to know what actually ran. Open AdStream brought delivery, targeting, analytics and contract management into one system.
That made 24/7 useful to people with different anxieties. Publishers wanted advertising revenue and control over inventory. Advertisers wanted relevant audiences and measurable results. Agencies needed technology that could turn a media plan into something executable. The company occupied the working space between a campaign’s ambition and its delivery.
One rectangle. Three jobs.
The distinction mattered competitively. DoubleClick also supplied advertising infrastructure; an ad network alone could not claim the same depth of integration. 24/7 combined its own software with publisher relationships and partner tools. Its expertise lay in operating the connections, as much as selling access to the audience.
Three ways to get paid
The revenue model followed those jobs. Media customers paid for advertising space, commonly by the thousand impressions. Publishers shared in the proceeds. Hosted Open AdStream customers paid service fees tied to impressions served, with additional charges for applications such as analytics and behavioral targeting. Search services added fees linked to spending or clicks, plus setup and maintenance charges for optimization.
This was a mix of software economics and advertising services. A campaign budget bought distribution; an ad-serving fee bought the mechanism. Those costs are easy to confuse, especially when one company supplies both.
WPP’s announced transaction value, net of cash acquired.
$11.75 per share.
WPP completed its acquisition in July 2007. The appeal included search marketing, digital media and technology skills. Reported 2006 revenue was approximately $200 million, up 43% from the previous year. An advertising holding company was buying tools that could support its wider client business, alongside a revenue-producing operation.
A shortcut to the other side
The next improvements were about reducing distance. Connect offered publishers a route to advertising buyers. A 2012 Microsoft partnership put exchange access inside Open AdStream and connected Microsoft demand to premium inventory. Publishers could reach another pool of advertising money through a system they already used.
Product work also addressed ordinary friction. A 2013 Open AdStream update added a customizable dashboard, simpler campaign workflows and a feature to reconcile delivery-report discrepancies. Less dashboard wrestling is a modest promise. For an operations team, it can be an attractive one.
In January 2014, 24/7 merged into Xaxis, joining publisher technology with audience-buying capabilities. The merger announcement described a combined business serving more than 2,700 clients and managing over $750 million in audience-targeted media. Those figures describe the combination. The 24/7 name had reached the end of its independent operating story.
Even the machinery had to move
Ownership had limits. In September 2014, AppNexus announced it would acquire Open AdStream from Xaxis, while WPP separately committed $25 million to AppNexus. Xaxis could concentrate engineering on media products, data and decisioning while retaining connections to publisher inventory through a partner.
“We can’t build every piece of the ad tech stack”
Brian Lesser, Xaxis CEO / September 2014
WPP’s 2024 filing places the acquired business’s lineage within Choreograph. The capabilities outlasted the name, but they did not remain bundled forever. Even a technology-ownership strategy needed a decision about which technology to own.
Copy the discipline, not the shopping list
The useful inference is to follow a recurring customer problem into the workflow. A publisher still needed to deliver and account for ads after the market lost enthusiasm for internet stocks. Solving that problem gave 24/7 something practical to rebuild around.
There are conditions attached. Software needs enough demand to justify its cost; integrations need willing partners; targeting depends on usable data and permissions. A weak advertising market still hurts the businesses serving it. The copyable move is to protect a capability customers need, then keep reconsidering its ownership. 24/7’s second act began with acquiring the machinery. Its next chapter required letting some of it go.
