When planners think about Digital 48-Sheets, the conversation usually starts with scale - who has the most frames, the widest footprint, the biggest network. But scale and reach aren't the same thing. And for campaigns where the primary KPI is unduplicated audience coverage, the numbers tell a more interesting story. Across the 470 towns covered by D48 operators in the UK, the question isn't just who is present - it's who is present somewhere no one else is.
The exclusivity picture
Of the 90 towns where i-media has a D48 presence, 59 are exclusive - towns where no other digital Out of Home operator in the format is active. That's a 66% exclusivity rate: two out of every three i-media D48 towns are towns you cannot reach through any competing operator. 59 of i-media’s 131 frames are exclusive, representing a higher ratio of impact per frame than most networks twice its size.
What the frame count doesn't tell you
The instinct in planning is to weight D48 schedules toward the operators with the most frames. On a pure volume basis, that logic is sound, but if a brand is already buying from the major networks, the incremental reach question becomes: where can we go that they don't?
Across those 59 exclusive towns, i-media is the only answer. Adding i-media to a D48 schedule that already includes the major operators doesn't just buy more of the same audiences - it extends the map into communities that wouldn't otherwise be reached in the format at all.
The forecourt geography, again
As with RD6, the exclusivity in i-media's D48 estate isn't accidental. The network is built around motorway service areas, EV hubs, and petrol forecourts - locations that sit in catchment areas distinct from the high streets, retail parks, and arterial routes that dominate the major operators' estates. The geographic logic that drives the exclusivity in the format is the same regardless of the frame size.
That means the incremental reach isn't a function of luck or gaps in competitor coverage. It's structural.
For a campaign where reach breadth and geographic coverage matter, 59 exclusive towns is a meaningful number. At a 66% exclusivity rate, i-media's D48 estate is - proportionally - one of the most efficient reach extensions available in the format.
The frame count is smaller. The new audiences aren't.
