#narrowcasting

Walk into a shop, a school, or even a coworking space, and you’ll often see screens showing menus, directions, news, schedules - a kind of visual pulse of what’s happening around you. That’s digital signage: a way for organizations to communicate with people in a space without handing out flyers or making announcements on a loudspeaker.

Digital signage isn’t just “pretty screens.” It’s communication that:

reacts to time and context,

keeps people informed,

replaces static posters with dynamic messages,

and can be updated from anywhere in the world.

Whether it’s welcoming visitors, showing schedules, sharing quick updates, or guiding people to where they need to be, digital signage turns blank screens into meaningful moments.

What digital signage systems actually do

At its heart, a digital signage system helps you manage content - the images, videos, messages, menus, alerts, announcements — and decides when and where that content shows up on screens you control.

Instead of manually switching USB sticks or plugging in external devices every time you want to update a screen, digital signage software lets you:

design or upload new content,

schedule it to play at certain times,

broadcast it to multiple screens, and

change it in real time from a laptop or phone.

This is especially useful in places like offices, schools, cafes, or public spaces where content needs to stay current and relevant without repeated manual effort.

Castit: an approachable digital signage platform

Castit is a digital signage software that embodies this idea and makes it easy, flexible, and often free to start. Instead of thinking about digital signage as a complicated tech project, Castit treats it as a creative and practical communication tool you can manage from a browser.

With Castit, you can:

create and schedule dynamic content,

manage screens from anywhere,

work with playlists and apps (like text, videos, news feeds),

and update displays in real time.

It’s designed so that someone without deep technical knowledge can still build professional-looking signage, which means your screens become an active part of how your space communicates, not just background decoration.

How it actually works day to day

Here’s what using Castit feels like:

Create content online. You add images, clips, text, or live web content in the Castit system, and organize it into playlists or schedules.

Assign screens. Any screen with Castit installed - whether it’s Windows, Android TV, Linux, or other supported devices - can receive and display the content.

Update from anywhere. Want to change today’s lunch menu, post a last-minute meeting alert, or show a welcome message? Just update it online, and Castit pushes it to your screens.

This setup transforms screens into dynamic communication hubs, without needing someone to physically walk around updating them.

Why this matters in everyday spaces

Digital signage isn’t just for big brands anymore. Offices use it to improve internal communication, schools use it for announcements and event updates, and cafés use it to show menus that change throughout the day. These screens become part of the rhythm of a place, helping people stay informed without extra noise or confusion.

Castit brings all of this together in a way that’s accessible for businesses of all sizes. You can start with the free tier and scale as you go, and explore Castit in different languages depending on your region - whether that’s Dutch, Serbian, or English.
