📰 This is what the upcoming advertisement in videos will look like. In videos will show a banner that will appear no more than once every 2 minutes, and you can close it 9 seconds after it appears. It will also appear only after showing the player with captions to multimedias – unknown. Advertising is limited to 160 characters and an external link can be embedded.
