Reddit has started testing a new feature that lets users watch or listen to popular posts rather than reading them. The experiment introduces audio and video formats to the platform's traditionally text-based content. The move appears to draw inspiration from short-form video platforms like TikTok. This shift signals Reddit's interest in broadening how its content is consumed beyond conventional reading.
Sonic Fire Protection, a startup developing sound-powered fire suppression technology, has raised $15 million in new funding.

The investment signals growing interest in alternative fire suppression methods beyond traditional sprinkler and chemical systems.
According to a report by Ars Technica, Amazon has been accused of discarding rare books as part of an AI training data operation. The claim reportedly came to light after a hidden AirTag tracking device was concealed within a book, revealing its fate. The full details of who placed the tracker, when this occurred, and the scale of the alleged destruction are not available from the provided source material. Amazon has not yet publicly responded to the allegations based on the information given. The story raises concerns about the use and potential destruction of rare literary materials in the development of artificial intelligence systems.

YouTube has updated its view-counting method so that a view is recorded as soon as a video begins playing. Previously, the platform used a different threshold before registering a view on standard videos. This policy change mirrors the approach YouTube already adopted for its short-form content, YouTube Shorts. The Shorts view-counting update had been implemented approximately one year before this latest change was rolled out to regular videos.
