The takeaway:

👉 Accommodating the radical right on immigration doesn’t win back voters.
👉 It alienates the progressive base.
👉 And it raises the salience of the very issue the radical right owns.
In short: it’s electoral self-harm.

One policy implication:
Moving beyond cross-ownership caps, regulators should adopt network-based assessments to identify actual loci of influence in hybrid media systems.

Key insight: Concentration is not inherently detrimental.
Institutional logic of ownership matters:

* Public/foundation ownership → pluralism & press freedom
* Private/family ownership → risks of instrumentalization

@rodneybenson.bsky.social's works have been an inspiration, of course

Case study: 🇩🇰 🇬🇷

* Denmark: concentrated (CR4 = 66%, HHI = 1376), but ownership influence dispersed via public service media & foundations
* Greece: fragmented, yet ultimate control consolidated in families/individuals with political & industrial ties

Our proposal rests on 3 pillars:
1️⃣ Trace full ownership chains to ultimate beneficial owners
2️⃣ Weight markets by audience attention shares
3️⃣ Apply network centrality (esp. Katz centrality) to assess influence distribution

Tales Tomaz @talestomaz.bsky.social · Sep 5

We advance a combined approach:
🔹 Economic concentration measures
🔹 Network analysis of ownership relations

This allows us to interrogate both market structure AND relational power.

Tales Tomaz @talestomaz.bsky.social · Sep 5

Standard metrics (CRn, HHI) remain useful but insufficient. They capture market shares, yet overlook:

* Cross-sector integration
* Beneficial ownership structures
* Owners’ power over audiences

How should we measure media power and concentration in hybrid media systems?

Mariia Aleksevych and I just published a new open-access article in Media and Communication @cogitatiomac.bsky.social with a methodological proposal: www.cogitatiopress.com/mediaandcomm...
