Yahoo! Ads Launches In-Stream Advertising for ABEMA

In a significant development within the digital advertising landscape, LINE Yahoo! Corporation has officially initiated the distribution of in-stream advertisements through its Yahoo! Ads platform. Starting today, advertisers can leverage the capabilities of in-stream ads on ABEMA, the innovative video streaming service operated by AbemaTV. This new feature is set to commence on January 28, 2026, with promises to expand the advertising reach in conjunction with the changing viewing habits of consumers.

Background of the Service Launch

As technology evolves, so too have consumer preferences for video consumption. With an increased reliance on various devices, from traditional PCs and smartphones to internet-enabled TVs, advertisers are increasingly seeking methods to deliver concise yet impactful promotional content. The in-stream advertising format allows brands to seamlessly embed advertisements within the context of captivating program content, addressing the growing demand for more integrated advertising approaches.

Recognizing these shifts, Yahoo! Ads has been enhancing the options available to advertisers since September 2025, when in-stream ads were first introduced. The addition of ABEMA as a distribution channel significantly widens the horizon for reaching audiences engaged with the platform, thereby allowing for a more targeted advertising strategy that aligns with specific product offerings and marketing objectives.

Advertisers can look forward to utilizing targeting capabilities, including genre specification, enabling them to tailor their outreach more effectively, ensuring that messages resonate with the intended audience.

Implementation Timeline

The rollout is set with key dates:

- January 22, 2026: Registration for Yahoo! Ads Deal ID for ABEMA advertising starts.
- January 28, 2026: Ads that have passed the review process will begin to be distributed.

These dates are subject to change, as driven by operational necessities. The Deal ID mechanism, which identifies particular trading conditions agreed upon between advertisers and ABEMA, facilitates the customization of campaign elements like duration, targeting requirements, and genre specifics.

Overview of In-Stream Advertising

The Yahoo! Ads in-stream advertising service presents a revolutionary way to engage with audiences by embedding video commercials directly into programming content streamed by video services. This feature significantly broadens the advertising avenues available, extending beyond just PC and mobile consumption to include connected TVs, which are rapidly gaining traction in household entertainment. Moreover, advertisers can select video lengths tailored to their specific product or service messages, ensuring that promotional content is as effective as possible.

Important Considerations

Currently, the use of in-stream advertising is limited to clients with assigned LINE Yahoo! sales representatives. For those who seek further information on the specifications or implementation methods, they are encouraged to reach out directly to their representatives. Furthermore, by February 2026, LINE Yahoo! plans to expand its offerings to include companies without dedicated representative support.

It is important to mention that viewable impressions for in-stream ads are counted as soon as a video begins playing, distinguishing this service from regular display advertisements that count impressions differently.

The information within this release is subject to change without prior notice, reflecting the dynamic nature of online advertising strategies.

In its mission to deliver a "WOW" life platform that injects daily amazement into users' lives, LINE Yahoo! remains committed to providing impactful digital experiences, leveraging the power of the internet to enhance convenience and enrichment in everyday living.
