Netflix has found a new use for artificial intelligence: keeping your online videos from buffering, Quartz reports from Mobile World Congress in Barcelona. That may sound superficial, but it will have big implications for data use.

The usual method for encoding online video compresses it uniformly for a specific internet speed. Videos for low-bandwidth connections are more compressed, leading to grainy images. Netflix has found a way to match the compression level to the scene's content, meaning an action scene gets more bandwidth than a low-movement scene.

The wireless impact: The new trick, called Dynamic Optimizer, is aimed at viewers who are increasingly using their mobile devices to view video, especially in emerging markets like India, Japan and South Korea.

Why it matters: The improved compression algorithms will use less capacity on carriers' networks. Netflix is one of the largest drivers of internet traffic and eats up an enormous amount of bandwidth, so freeing some of that up will improve Netflix's historically tense relationship with the companies it relies on to reach consumers.

Amateur fireworks and small backyard cookouts are winning the weekend as the coronavirus takes the flash out of the Fourth of July.

What's happening: Public parades and fireworks displays around much of the country are being cancelled to prevent mass gatherings where the virus could spread. Hot-dog contests and concerts will play to empty stands and virtual audiences — all while American pride treads an all-time low.
