It still is, but nobody cares anymore. At 16:9 1920x1080 is considered "Full High Definition," and 3840x2160 (at minimum) is "Ultra High Definition," at least in terms of their official marketing speak. The latter has mutated to include both 4K and 8K content somehow, apparently because the brainworms in the marketing department ran out of superlatives after "Ultra."
All about aspect ratio, at a high aspect ratio 720 looks fine on a reasonably sized TV.
Do you know what aspect ratio means?
What is an example of a low and high aspect ratio?
