Screen advertisements are more common in games or video apps, such as the Defending Radish APP shown below. In-screen advertising is divided into static pictures and GIF pictures, which are generally precise advertising promotion forms with stronger visual impact and better advertising effect. Advertising effect is generally negatively correlated with user experience. Screen insertion advertising is better and more profitable than banner advertising, but it affects the user experience.

On mobile video platforms such as iQiyi Youku, there are two common advertising forms: patch and corner label.

Patch: If you are not a member, you will generally see short video advertisements pushed accurately before the video starts. The picture below is a screenshot of the patch advertisement of iQiyi APP.

It is a smart choice to let the audience skip the patch advertisement after watching it for a few seconds. Even if the audience doesn't like it, they are forced to watch it, which leads to poor user experience and no benefit to advertisers. It is better to allow users to jump, and judge which kind of advertisements this user is more interested in by marking the jumping time point, so as to achieve more accurate advertisement push.

Corner marker: an advertising form that appears next to the video playing window in a transparent style, and generally has a dynamic effect to attract users' attention during viewing. Allows users to turn off corner markers.

But this is definitely unreasonable and legal, because there is nothing that stipulates that an APP must have an open-screen advertisement, because many foreign softwares do not have open-screen advertisements. With this advertisement, the user's experience will be poor, and users will be lost, so most foreign software is not available. Although our experience is particularly poor, because most domestic software has open-screen advertisements, everyone is used to it and doesn't fight for it.
