This paper analyzes a real public company using its published annual report, a public court ruling and public statements; figures are for fiscal year 2024.
Week 1 identified Alphabet's central strategic question: how to keep search profitable, lead in AI-based information services and satisfy regulators at the same time. This paper examines the external conditions behind that question. For twenty years, the forces around Google Search were unusually kind; in 2024, two of them shifted at once. Porter (2008) argues that industry structure, shaped by five competitive forces, determines how much profit is available and where a firm is vulnerable. The analysis below applies that framework to Alphabet's two largest industries.
Search Advertising
In 2024, roughly $198 billion of revenue, more than half the company total, came from search and related advertising (Alphabet Inc., 2025).
Threat of new entrants: low, but rising
Building a general search engine requires indexing the web, enormous computing capacity and years of data about what users click. Scale economies and the default placement agreements Google holds on browsers and phones have kept entry very difficult. Generative AI lowers part of that barrier: a new company can offer answers to questions without building a traditional search index, using large language models trained on public data.
Bargaining power of suppliers: moderate to high
Alphabet's key suppliers include the companies that control access to users. Google pays device makers and browser developers to be their default search engine; these traffic acquisition costs exceeded $50 billion in 2024, and payments to Apple are among the largest (Alphabet Inc., 2025). Suppliers of AI chips hold power as well, which Alphabet reduces by designing its own tensor processing units.
Bargaining power of buyers: low to moderate
Advertisers are numerous and individually small, and search advertising reaches people at the moment they are looking for something, which is hard to replace. But large advertisers can shift budgets to other platforms, such as Amazon for product searches and social media platforms for discovery.
Threat of substitutes: high and growing
Generative AI assistants from OpenAI, Microsoft and others let users ask questions and get synthesized answers without visiting a search results page. Younger users also search on social video apps, and shoppers often begin on retail sites. Substitutes are the force most likely to change the industry's profitability, because every question answered without a results page is one fewer place to show an ad.
Rivalry: low in traditional search, high in AI assistants
Google has held a dominant share of general search for many years. In AI assistants, rivalry is intense, with several well-funded competitors releasing new models frequently.
Cloud Computing
Google Cloud produced about $43 billion of revenue in 2024 and became solidly profitable (Alphabet Inc., 2025). The industry's structure differs from search. Rivalry is high: Amazon Web Services and Microsoft Azure are larger and compete aggressively on price, services and AI tools. Buyers, especially large enterprises, have significant power because they negotiate multiyear contracts and can split workloads across providers. Barriers to entry are very high because of the capital required for global data centers. Alphabet is a challenger in this industry rather than a leader.
The General Environment
Legal and political
In United States v. Google LLC, decided in 2024, a federal district court ruled that Google had unlawfully maintained monopolies in general search and search text advertising, largely through exclusive default agreements. Remedies ordered in 2025 limited such exclusive arrangements. In Europe, the Digital Markets Act designates Alphabet as a gatekeeper subject to rules on self-preferencing and data use. Legal constraints now reach the agreements that protected Google's distribution.
Technological
Generative AI is both the largest threat and Alphabet's largest opportunity. Alphabet's own research labs developed the transformer architecture that underlies today's large language models, and the company has integrated AI-generated overviews into search results.
Economic
Advertising spending rises and falls with the economy, so Alphabet's revenue is exposed to downturns, while AI infrastructure requires tens of billions of dollars a year in capital spending regardless of the cycle.
Social and environmental
Public concern about privacy, misinformation and AI safety shapes regulation and user trust. And AI computing requires large amounts of electricity, raising Alphabet's energy use and making its emissions goals harder to reach.
Opportunities and Threats
The scan can be summarized as the opportunities and threats that will feed the SWOT analysis in Week 3. The main opportunities are growing enterprise demand for cloud computing and AI tools, where Alphabet can sell its models and chips to other companies; new advertising formats inside AI-generated answers and on connected television through YouTube; and subscription revenue from services such as YouTube Premium and paid AI plans, which reduces dependence on advertising. The main threats are AI assistants that answer questions without a results page; legal remedies that weaken default placement on browsers and phones; regulation in Europe and elsewhere that limits how Alphabet combines data across its services; the rising cost of computing infrastructure, which could squeeze margins if AI answers prove less profitable than traditional search advertising; and the environmental and political scrutiny that comes with building energy-intensive data centers. The weight of the threats falls on search, which produces most of the profit, while the weight of the opportunities falls on cloud and subscriptions, which are growing but smaller. That imbalance is the external reason Alphabet cannot simply defend its current position.
Implications for Competitive Advantage
Two conclusions follow. First, the two forces that most threaten Alphabet's core advantage are substitutes, through AI assistants, and the legal environment, which limits the default agreements that protected its distribution. Second, Alphabet's advantages in AI research, computing infrastructure and its own chips position it to compete in the substitute market rather than only defend against it. The strategic question sharpens: can Alphabet move its users to AI-assisted search while keeping an advertising model that works there?
Conclusion
Alphabet's search business sits in an industry with high barriers and weak buyers, which has supported extraordinary profits. But substitutes from generative AI and legal limits on default agreements have weakened two of the forces that protected it, while its cloud business competes against larger rivals. Week 3 will turn inward to the resources and capabilities Alphabet can use to respond.

How this MGT 498 Week 2 example is structured
The University of Phoenix library guide for MGT/498 lists Week 2 as Building a Competitive Advantage, and many sections work the external side of the analysis. The paper analyzes two industries separately, because Alphabet competes in markets with very different structures. Each force is rated with evidence, and the general environment scan concentrates on the conditions most likely to change the forces, which is what the strategy in later weeks must answer. Students search this week as MGT 498 Week 2, MGT498 Wk 2 or MGT/498 Wk 2; all three are the same assignment.
MGT/498 Week 2 questions, answered
What does MGT/498 Week 2 usually ask for?
The University of Phoenix library guide for MGT/498 lists Week 2 as building a competitive advantage. Many sections ask students to analyze the external environment of the case company, often using Porter's five forces and a general environment scan, and to explain how it affects competitive advantage.
What are Porter's five forces?
The threat of new entrants, the bargaining power of suppliers, the bargaining power of buyers, the threat of substitute products or services and rivalry among existing competitors. Together they determine how much profit an industry can earn and where a firm's advantage is most exposed.
Why analyze more than one industry for Alphabet?
Because Alphabet's businesses compete in different industries with different structures. Search advertising is dominated by Alphabet, while cloud computing has strong rivals that are larger. Treating them as one industry would hide these differences.
