Key Takeaways 

‍

• AVOD offers greater viewer control, supporting on-demand access and personalised discovery 
• FAST enables broad reach quickly, using curated channels and existing content libraries 
• AVOD drives higher ad precision, through targeted, data-led advertising 
• FAST supports scalable distribution, with continuous inventory and simple channel-based delivery 

‍

Understanding the difference between FAST and AVOD is becoming essential as streaming models continue to evolve. Both offer free, ad-supported content, but they serve different purposes depending on the end goal. 

Choosing the right model or combining both can help you maximise each area of your offering in an increasingly competitive streaming landscape. 

What are Free Ad-Supported TV (FAST) Channels? 

Free Ad-Supported TV (FAST) channels are linear streaming services that deliver programming alongside advertising, without subscription fees. Unlike AVOD platforms, FAST mimics broadcast TV with curated, always-on channels. This model gives a familiar feel to viewers while optimising free content.  

Pros of FAST channels

• Free access removes subscription barriers, attracting large audiences
• Lean-back channels simplify content discovery and viewing
• Continuous ad inventory enables scalable revenue
• Content libraries can be repurposed, extending value

Cons of FAST channels 

• Ad load can disrupt viewing experience and reduce engagement 
• Limited on-demand control compared to AVOD platforms 
• Content quality varies due to reliance on library programming 

What are Advertising-based Video on Demand (AVOD) Channels?

Advertising-based Video on Demand (AVOD) channels provide free access to content that viewers can watch anytime, supported by advertising rather than subscription fees. Unlike linear streaming, AVOD allows users to choose specific titles from a content catalogue, enabling flexible viewing and personalised discovery while generating revenue through targeted, data-driven advertising.

Pros of AVOD channels 

• On-demand viewing gives users full control over what and when they watch
• Targeted advertising enables more precise monetisation and higher potential ad value
• Personalised recommendations improve content discovery and audience engagement
• Flexible content libraries support diverse programming and long-term viewer retention

Cons of AVOD channels

• Revenue depends heavily on advertising demand and audience data quality
• Content discovery can be challenging without strong search and recommendation systems
• Platform and infrastructure costs can increase as content libraries grow
• Audience engagement may vary depending on content availability and competition

Key differences between FAST vs AVOD   

The key differences between FAST and AVOD is in content delivery. 

FAST channels are presented in a scheduled linear model while AVOD offers on demand viewing. Each makes revenue through different models with FAST having continuous slots like traditional TV while AVOD has targeted on-demand ad placements. 

‍

1. Viewing experience 

FAST channels replicate traditional television with linear, scheduled programming designed for passive, lean-back viewing. AVOD platforms, however, provide on-demand access, allowing users to choose specific titles anytime. These differences impact user behaviour, with FAST encouraging channel surfing, while AVOD supports intentional viewing  with selected content libraries.

Real-world deployments demonstrate how FAST continues to evolve the traditional TV experience in digital environments. For example, Simplestream enabled CBS and AMC Networks UK channels to launch Server-Side Ad Insertion (SSAI) on Freely in partnership with Sky Media, ensuring seamless ad delivery that maintains a broadcast-quality viewing experience across connected platforms. 

This illustrates how modern FAST infrastructure can preserve the familiarity of linear TV while delivering the reliability and scalability expected in streaming.

2. Content structure 

FAST channels organise content into themed, always-on streams. AVOD platforms host large, searchable libraries where users select individual titles. This means FAST emphasises curation and flow, whereas AVOD prioritises content depth, variety, and user-driven discovery through recommendations and search functionality. 

This distinction is particularly visible in international channel launches and market expansions. For instance, Simplestream supported Sony One’s expansion into Latin America, enabling the rapid deployment of curated FAST channels tailored to regional audiences. 

Similarly, services such as GAAGO, the global Gaelic games streaming platform, demonstrate how structured content delivery can combine linear-style channels with on-demand viewing to serve niche audiences effectively. These examples highlight how content structure decisions directly influence scalability and audience engagement strategies.

3. Monetisation model 

Both FAST and AVOD rely on advertising, but execution differs significantly. FAST generates revenue through continuous ad breaks within linear streams, similar to broadcast TV. AVOD platforms monetise through targeted, dynamic ad insertion based on user behaviour, often achieving higher CPMs due to better segmentation, measurement capabilities, and personalised advertising opportunities. 

Operational deployments show how advanced ad technology can enhance monetisation across both models. For example, the SSAI implementation for CBS and AMC Networks UK demonstrates how reliable, server-side ad delivery supports consistent revenue generation while maintaining a smooth viewer experience. 

Meanwhile, platforms such as Blaze, operated by A+E Networks EMEA, have enhanced their streaming services through modernised ad workflows and platform infrastructure, enabling more efficient monetisation across digital channels.

4. Content strategy 

FAST channels often rely on library and archival content, maximising value from existing catalogues with minimal incremental cost. AVOD platforms increasingly invest in original programming and exclusive titles to attract and retain audiences. This results in FAST being cost-efficient and scalable, while AVOD competes more aggressively on content differentiation and exclusivity. 

In practice, many services adopt hybrid strategies that balance efficiency with audience growth. Retail-focused streaming platforms such as TVSN NOW, for example, leverage continuous streaming channels to drive engagement and commerce without the high production costs associated with original content. 

Similarly, broadcasters launching FAST services can quickly monetise existing catalogues while expanding distribution into new markets. These approaches demonstrate how FAST enables rapid channel launches and scalable growth while preserving flexibility in long-term content investment strategies.

FAST vs AVOD: Which is the right fit 

FAST is the right choice when you are looking to capture passive viewers in a more traditional linear way, look for AVOD when you seek control and on-demand flexibility. 

When to choose FAST 

Choose FAST when you want to reach audiences quickly with content you already have and keep things simple. It’s great for a more traditional, casual viewing experience, helping you engage viewers without heavy investment in new production or complex personalisation, while still generating steady ad revenue over time. 

When to choose AVOD 

Choose AVOD when you want to give viewers more control over what they watch and when. It’s a strong fit if you’re investing in content discovery, personalisation, and targeted advertising, helping you deliver a more tailored experience while maximising ad value through better audience insights and engagement. 

When to combine FAST and AVOD

Choose both when you want the best of both worlds. FAST helps you reach wider audiences and drive discovery, while AVOD gives viewers control and deeper engagement. Together, they let you maximise content value, extend viewing time, and create more opportunities for targeted, scalable ad revenue across different audience behaviours.
