YouTube AdsWide moat

Alphabet (Google) (GOOGL) — moat facet

The most-watched distributor on American television still grows its advertising more slowly than Google's search engine; that gap is the whole opportunity.

YouTube is the only Alphabet business that competes for the living-room screen, and on that screen it now leads. In May 2026 it took 13.8% of all U.S. television watch time, "the largest share of television among all distributors for a third consecutive month", ahead of Disney at 10.0% and Netflix at 8.0%1. Its advertising brought in $40,367 million in 20252, a tenth of Alphabet's revenue, and that figure understates YouTube's size because its subscription money is booked on a different line.

YouTube is the largest single distributor on American television, yet its ad revenue still grows more slowly than Search: the screen lead has not yet become a revenue lead.

Google agreed to buy YouTube in October 2006 for $1.65 billion in stock3. The price was paid for a young video site with a very large audience and no proven way to make money from it. Alphabet's annual reports break out YouTube's advertising from 2017, when it was already $8,150 million a year4. Eight years later it was almost five times that size, a compound rate of about 22%5.

The line is the ads that play before, during and beside videos on YouTube's own properties. Alphabet sells two kinds. Brand advertising buys attention, as television spots do; direct response advertising buys an action, such as a click, an install or a sale. In 2025 the filing credits growth to "direct response advertising products followed by our brand advertising products"6, which is the more durable order, because an advertiser that can measure a sale tends to keep spending when budgets tighten. The same auction machinery that prices search ads sets the price, but what is being sold is attention rather than a stated want.

YouTube's costs are what separate it from Search. It does not own most of what it shows; it shares the advertising with the people who make the videos. Alphabet describes these payments as content acquisition costs, "primarily related to YouTube", within its cost of revenues7, and YouTube says it has paid out over $100 billion to creators, artists and media companies since 20218. The same announcement said the number of channels making more than $100,000 from TV screens had jumped 45% in a year. That payout is the reason the library keeps growing without YouTube commissioning it, and also the reason YouTube's margin is structurally lower than a search page's. Alphabet does not disclose YouTube's profit; it sits inside Google Services, whose 2025 margin was about 41%9.

The growth record has one clear stall. In 2022 YouTube ads went from $28,845 million to $29,243 million, up just 1.4%10. Growth came back at about 8% in 2023, 15% in 2024 and 11.7% in 202511. The latest quarters sit in the same range: 11% in the first quarter of 202612 and 13% in the second, to $11,055 million13. For a business that leads American television, that is solid rather than spectacular, and it is slower than the 25-year-old search engine beside it.

The outlook turns on converting the television lead into television money. YouTube's argument to advertisers is that its audience is now the largest single one on the screen, and that the budgets built around network television should follow it. It has also started to buy the kind of programming that television networks built their franchises on: the NFL's Sunday Ticket package came to YouTube in a seven-year deal of about $2 billion a year, available from the 2023-24 season14. That cost and the subscription revenue sit on the subscriptions line; what the deal buys this line is one more reason for a living-room audience to open YouTube. The risk is that a larger share of viewing goes to formats that are harder to sell against, such as short clips, or to the ad-free tiers. YouTube Music and Premium had 125 million subscribers, including trials, by March 2025, and in the same announcement YouTube widened a cheaper Premium Lite pilot to users in the United States15. That money lands on the subscriptions line, and every hour watched without ads is an hour this line cannot sell, which is why YouTube's advertising and its subscriptions have to be judged together.

The test is simple. YouTube ads grew 11.7% in 2025 against 13.4% for Search & other16, and 13% against 17% in the second quarter of 2026, the quarter in which YouTube recorded its best-ever share of TV viewing. If the most-watched distributor in American television cannot grow its advertising faster than a mature search business, it would suggest advertisers still value a YouTube hour below a network one, and the gap between watch-time share and ad growth is the number to follow.

Moat trajectory: Widening

YouTube reached a record 13.8% of U.S. TV watch time in May 2026, the largest of any distributor for a third straight month, and its ad growth recovered from 1.4% in 2022 to 11.7% in 2025 and 13% in the second quarter of 2026. The lead on the television screen is growing faster than the revenue that follows it.

YouTube leads American television viewing ahead of Disney (10.0%) and Netflix (8.0%), yet its ad revenue grew 11.7% in 2025 against 13.4% for Search. Watch whether ad growth catches up with the screen-share lead.
