Creating the Fan Economy: C5G Interactive Live Sports

How Castanet helps sports teams of every tier turn live games into participatory, direct-to-fan experiences — in the stadium, at home, and on the go.

In previous posts we have explored the unique performance characteristics and economics of the Castanet 5G Broadcast Internet network. We have discussed how we leverage our breakthrough network scale and cost with our Castanet engagement platform and related application services. The Castanet app platform consists of composable building blocks that allow us to create a wide range of immersive end user experiences. In this post we explore C5G Interactive Live sports as one example of the type of experiences that can be built when a powerful network and an app platform work together to amplify the value of your content.Live sports is the most valuable content in the world and the least compatible with the unicast internet. As audiences grow, delivery costs rise and quality degrades. Fans expect more than passive viewing. They want interaction, participation, community, and a direct connection to the teams they follow.

C5G Interactive Live Sports is Castanet’s answer. Built on the Castanet 5G Broadcast Internet and its engagement platform, C5G turns live sports into immersive, interactive experiences across mobile and prime screens. It replaces passive viewing with real-time engagement, community, and commerce at any scale.

THE GOAL

Create a fan economy on the Castanet 5G Broadcast Internet — where growth in viewership creates value, not escalating costs, and fans are active participants rather than mere viewers.

One Platform, Two Needs

Sports teams face different distribution problems depending on their tier, but the underlying need is the same: reach and engage fans directly, own the relationship, and grow franchise value without being constrained by last-mile economics or platform intermediaries.

Tier 1: Own the Fan Experience

Major professional teams and leagues already have media agreements. Many also face the ongoing challenges of regional sports networks — rights structures that limit digital control and leave teams without a clean path to own the interactive relationship with their fans.

C5G enables Tier 1 teams to activate interactive digital rights at national scale through broadcast-powered second-screen experiences. These complement existing media agreements rather than compete with them. Real-time interaction, social engagement, and synchronized data transform live games into participatory events. Teams deepen fan relationships while unlocking new sponsorship, engagement, and direct-to-fan monetization opportunities — without disrupting the primary broadcast.

Tier 2 and Tier 3: Reach That Was Previously Out of Reach

Lower-tier teams and leagues often own their rights but lack the distribution and economics to reach fans at scale. Traditional streaming is expensive, fragile under load, and gets worse as audiences grow.

C5G enables these teams to deliver full interactive live streaming directly to fans at any scale, without the cost, congestion, or complexity of unicast. Broadcast-powered delivery combined with real-time interaction, social features, and built-in commerce turns games into engaging, monetizable experiences. Flat delivery economics mean teams can grow their communities without fear that success will destroy margins.

Frictionless Direct Engagement, Everywhere

The Castanet 5G Broadcast Internet is what makes the experiences possible at scale. Content is delivered once, directly to the device, in consistent quality independent of network load. Because 5G Broadcast is a 3GPP standard and a native phone feature, reception requires no SIM card and does not consume the user’s data plan. There are no data caps on the broadcast path.

That means perfect live streams and recorded video — highlights, full-game replays, behind-the-scenes content — can reach fans:

• In the stadium, as a second-screen companion that keeps fans in the moment

• At home, on the big screen or a mobile device

• On the go, on the phone, without draining a data plan

No fragmentation. No buffering under load. Shared live moments at any scale. This is the digital stadium, delivered direct-to-fan.

From Viewers to Active Participants

C5G is not only a delivery network. The engagement platform is designed to create engaging fan experiences jointly with teams and leagues. Interactive and social features drive audience growth and engagement. Gamified experiences work both online and in-venue.

Examples of what the platform enables:

• Real-time interaction synchronized with the live action

• Voting, polls, and predictions that turn passive watching into participation

• Social features that connect fans to each other and to the team

• Gamified experiences and leaderboards that extend engagement before, during, and after the game

• Second-screen features that complement a primary broadcast or stand alone

Engagement becomes social, emotional, and continuous. Stronger communities create stronger loyalty. Fans are no longer just viewers. They are active participants in the event.

Monetization Built on Fandom, Not Extraction

The goal is not to extract maximum value from fans. It is to create genuine fan experiences and fandom — and then give teams the tools to monetize that relationship in ways that feel natural and valuable.

Teams and leagues decide if and how to monetize. The Castanet platform supports multiple models on the same delivery fabric:

• FAST channels — free, ad-supported experiences that work economically because delivery cost stays flat as the audience grows

• Multiple subscription tiers — free, premium, or team-specific access

• Pay-per-view and event access for marquee moments

• Sponsorships and branded activations inside the experience

• Premium access and fan rewards

Integrated eCommerce is linked to key moments in the stream. A goal, a highlight, a celebration can trigger the purchase of a jersey, a ticket, or related merchandise. Transaction fees and in-moment commerce expand revenue opportunities while establishing a direct-to-fan relationship. Every interaction becomes an opportunity to grow revenue and deepen the connection.

Castanet works with content owners on revenue-share agreements. Shared risk. Shared reward. You bring the content. We bring the network and the technology. Together we profitably grow your audience.

Increasing Franchise Value

Interactive experiences unlock new monetization models — from eCommerce built into key moments to fan rewards, digital collectibles, sponsorships, and premium access. This is how franchises scale in a fan-driven economy.

For Tier 1 teams, C5G provides a path to own the interactive relationship even when primary media rights sit elsewhere. For Tier 2 and Tier 3 teams, it provides the distribution and economics that make direct-to-fan viable for the first time. In both cases, the combination of perfect delivery and participatory experiences creates a durable asset: a direct relationship with fans that grows in value as the audience grows.

A Better Way to Stream. A Better Way to Grow the Game.

For decades, live sports distribution has been constrained by artificial limits — limited streaming capacity, escalating delivery costs, and closed ecosystems that reward gatekeepers more than teams or fans. C5G is collaborating with leagues and teams to build the Fan Economy, shifting the model from extraction to fan participation.

The Castanet 5G Broadcast Internet provides the scalable, flat-cost foundation. The engagement platform provides the interactive, social, and gamified layer. Together they let sports teams of every tier create fandom - in the stadium, at home, and on the go - and turn that fandom into a sustainable fan economy.
