Porter's Five Forces

Porter's Five Forces (Michael Porter, 1979) is the foundational framework for analysing industry attractiveness and competitive dynamics. It examines five structural forces that determine the profitability potential of an industry. The stronger these forces, the more competitive pressure exists and the harder it is to earn sustainable profits. For marketers, understanding these forces is essential for strategic positioning and identifying where to compete.

When to use this framework

→Entering a new market or evaluating market attractiveness
→Annual strategic planning and competitive analysis
→Presenting market dynamics to the board or leadership team
→Evaluating whether to invest in or exit an industry
→Understanding why margins are compressing or expanding

Worked Example

Netflix (Streaming Video, 2024)

1. Competitive Rivalry

Intensity of Rivalry

How intense is competition among existing players? Consider: number of competitors, industry growth rate, product differentiation, exit barriers, and fixed costs.

Extremely intense. Major competitors include Disney+, Amazon Prime Video, HBO Max, Apple TV+, Paramount+, and Peacock. Industry has shifted from growth-at-all-costs to profitability focus, leading to price increases and ad-supported tiers. Content spending remains high ($15-20B/year for top players). Limited product differentiation beyond content library. High fixed costs (content production) create pressure to scale.

Force Strength

Rate this force: Low, Medium, or High.

High

2. Bargaining Power of Buyers

Buyer Power

How much power do your buyers have? Consider: buyer concentration, switching costs, price sensitivity, information availability, and ability to backward integrate.

Moderate to High. Low switching costs (consumers can subscribe/cancel monthly). Many alternatives available at similar price points ($7-16/month). Growing 'subscription fatigue' — average household willing to pay for only 3-4 services. However, unique original content creates some lock-in (you can only watch Stranger Things on Netflix).

Force Strength

Rate this force: Low, Medium, or High.

Medium-High

3. Bargaining Power of Suppliers

Supplier Power

How much power do your suppliers have? Consider: number of suppliers, uniqueness of inputs, switching costs, and supplier ability to forward integrate.

Moderate. Key suppliers are talent (actors, directors, showrunners) and content studios. Top talent commands enormous fees and can choose between platforms. However, Netflix's in-house production capabilities (Netflix Studios) reduce dependency. Music licensing and technology infrastructure (cloud computing) have moderate supplier power.

Force Strength

Rate this force: Low, Medium, or High.

Medium

4. Threat of Substitutes

Threat of Substitutes

What alternatives could customers switch to that solve the same problem differently? Consider: price-performance of substitutes, switching costs, and buyer propensity to substitute.

High. Substitutes include: free ad-supported streaming (YouTube, Tubi, Pluto TV), social media video (TikTok, Instagram Reels), gaming (PlayStation, Xbox, Nintendo), live TV/sports, piracy, and simply doing other leisure activities. TikTok's short-form content is capturing time and attention away from long-form streaming, especially among younger demographics.

Force Strength

Rate this force: Low, Medium, or High.

High

5. Threat of New Entrants

Threat of New Entrants

How easy is it for new players to enter your market? Consider: capital requirements, economies of scale, brand loyalty, regulatory barriers, and access to distribution.

Low-Medium. Barriers to entry are significant: content production requires billions in investment, global distribution infrastructure is complex, and building a content library takes years. However, major tech companies (Apple, Amazon) can absorb streaming losses and subsidise entry. Regional players (Jio in India, iQIYI in China) can enter local markets effectively.

Force Strength

Rate this force: Low, Medium, or High.

Low-Medium

6. Overall Industry Assessment

Overall Assessment

What do the five forces tell you about the attractiveness of this industry? Which forces are most critical? What strategic actions can you take to improve your position?

The streaming industry is structurally challenging: high rivalry, strong buyer power through low switching costs, and significant substitute threats from free alternatives and short-form content. The industry's profitability depends on achieving scale and reducing churn through must-have original content. Netflix's strategic responses: (1) Invest in global original content that can't be substituted, (2) introduce ad-supported tier to capture price-sensitive segments, (3) crack down on password sharing to convert freeloaders to subscribers, (4) expand into gaming and live events to increase engagement and reduce substitution risk. The key strategic insight: content quality and volume remain the primary competitive moat in an industry with low switching costs.
