HBO Max has begun testing a vertical short-form video feed and an AI conversational search feature with some users in the United States. The Shorts icon in the app shows trailers, scene clips and bonus videos in a personalised vertical feed based on viewing history. AI is also used to select clips, with an AI tool analysing films and TV programmes before editors choose final clips. The company plans to expand both tests to more devices and markets.

Bitcoin is not a standalone invention by Satoshi Nakamoto but a product combining ideas accumulated in the cypherpunk community since the late 1990s, a claim has emerged.

He said Satoshi’s achievement was solving double spending and unifying dispersed concepts into an operating protocol.
