Direct Answer
Comcast reports revenue across 5 business segments in its fiscal 2025 Form 10-K. Residential Connectivity and Platforms is the largest, with $70.7 billion of revenue (57% of the total), followed by Media at $27.1 billion (22%). 77% of revenue came from the United States.
How Does Comcast Make Money?
No single line supplies a majority of revenue: the largest, Residential Connectivity and Platforms, is 57%, which spreads Comcast's exposure across several demand drivers. Between fiscal 2024 and 2025, Theme Parks grew fastest (+14.1%) and Media slowest (-3.8%), so the revenue mix tilts toward Theme Parks while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Residential Connectivity and Platforms | $70.7 billion | $71.6 billion | 57.2% | -1.2% |
| Media | $27.1 billion | $28.1 billion | 21.9% | -3.8% |
| Studios | $11.3 billion | $11.1 billion | 9.1% | 1.7% |
| Business Services Connectivity | $10.2 billion | $9.7 billion | 8.3% | 5.5% |
| Theme Parks | $9.8 billion | $8.6 billion | 8.0% | 14.1% |
Where Does Comcast's Revenue Come From?
Regions follow the definitions in the filing; most companies assign revenue by customer location.
| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| United States | $95.1 billion | $96.2 billion | 76.9% | -1.1% |
| United Kingdom | $15.2 billion | $14.2 billion | 12.3% | 7.0% |

What the Segment Figures Do Not Show
The rows above add up to 104% of Comcast's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Comcast reported in the segment note and revenue disclosures of its Form 10-K filed February 3, 2026 (accession 0001628280-26-004994), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
