Sizing up Netflix's, YouTube's, and Amazon's streaming viewing and advertising

To understand how streaming viewing and advertising align, we analyzed various services’ ad revenues and time spent estimates. Our ad revenue figures come from Insider Intelligence forecasts. Time spent estimates come from Nielsen’s The Gauge. Among our findings:

Netflix’s time spent exceeds its ad revenues the most. Netflix accounts for more than one-fifth of total streaming time spent, but because it has so few viewers on its new ad plans, it will represent just 2.5% of US CTV ad revenues in 2023. This indicates that, due to its massive userbase, Netflix has the most potential to expand ad revenues.

YouTube leads in time spent and ad revenues. On a gross basis, it accounts for nearly one-fourth of total US CTV ad revenues and streaming time spent. YouTube is operated by the world’s largest ad seller, the vast majority of its viewers use the free ad-supported version, and the service features heavy ad loads, which contributes to heightened ad revenues.

Amazon will make a big splash in streaming advertising. In September, Amazon announced that Prime Video will have ads by default beginning in early 2024 in the US, UK, Germany, and Canada. The move could shake up the market. Amazon estimated that ads on Prime Video will reach more than 115 million US viewers per month, according to a pitch deck obtained by Insider.

Streaming services operate under various business models, so comparing them isn’t exactly apples to apples. A streaming service that underindexes on advertising may be doing so intentionally because it relies most on subscription fees to fund content production and it doesn’t want to increase churn by opening up the advertising firehose too widely. Meanwhile, other services are free and serve ads to all viewers. Notable issues affecting streaming usage and revenue comparisons include advertising loads, prices, and sign-up rates.
