How Media Agencies Are Changing the Way Digital Screens Are Bought

The way advertising on digital screens is purchased is changing.

Not because the screens themselves are different or because media owners need to abandon their traditional sales model, but because media agencies are adopting new tools to plan and execute campaigns more efficiently.

In this process, DSPs are becoming increasingly relevant.

Understanding this shift allows screen network operators to anticipate change and prepare their inventory for new ways of buying media.

The Change Is Happening on the Buyer Side

For years, a large share of out-of-home advertising was purchased through direct processes: sales contacts, proposals, location lists, negotiations, and purchase orders.

That model is still very much in place.

At the same time, however, media agencies are adopting digital platforms that allow them to plan and execute media buys from a single environment.

This is where DSPs come in.

A DSP (Demand-Side Platform) is a tool used by agencies and media buyers to manage the purchase of advertising inventory in a more centralized way.

Instead of evaluating each opportunity separately, buyers can work from a platform that allows them to search for and plan available inventory according to the needs of a campaign.

Why Do DSPs Make Buying Easier?

The main advantage is reducing manual processes.

When a media agency needs to plan a campaign across different markets, working with long location lists, static files, or multiple commercial exchanges can slow the process down.

Digital tools make it possible to organize that planning differently.

Buyers can search for inventory, identify locations, and evaluate options directly from the platforms they already use to manage their campaigns.

That is why this shift does not depend only on agencies adopting new technology.

It also requires media owners’ inventory to be properly found and interpreted by these tools.

A Network Can Have Many Screens and Still Be Difficult to Buy

For a media owner, having a large screen network is a commercial advantage.

But when planning takes place through digital platforms, simply stating how many screens are available is not enough.

The buyer needs to understand what inventory actually exists.

For example:

• where each screen is located;
• what format it has;
• its resolution;
• the characteristics of each media asset;
• what inventory is available.

The clearer and more structured this information is, the easier it becomes to incorporate the network into new planning processes.

Digitizing media buying also means preparing inventory to be understood digitally.

What Does This Change Mean for a Media Owner?

It does not mean giving up direct sales.

Programmatic buying can coexist with the agreements, clients, and campaigns that media owners already manage through their sales teams.

What emerges is an additional opportunity: allowing certain buyers to access inventory through the tools they already use.

To participate, the network needs to be technically prepared to connect with those platforms.

The media owner still decides which spaces to offer and under what conditions.

Technology simply allows that inventory to also become available through new ways of planning and buying media.

Preparing Before the Campaign Arrives

The way media is bought does not change overnight.

But as agencies and media buyers continue incorporating digital tools into their processes, media owners need to make sure their networks can keep up with that evolution.

That means having inventory properly identified, keeping information up to date, and having the necessary integrations in place to connect with programmatic supply platforms.

It is not about changing the entire business.

It is about avoiding a situation where a buying opportunity reaches a network that is not yet ready to receive it.

The Role of Doohmain

Doohmain connects screen networks precisely and efficiently to SSPs, the platforms that make inventory available for programmatic buying.

On the other side, media agencies and other buyers can use their DSPs to plan and execute campaigns.

This allows media owners to continue managing their existing operations while preparing their networks to participate in new ways of buying media.

The way media owners sell is not disappearing. The way buyers purchase media is evolving. And having your inventory ready means being prepared when that opportunity arrives.
