True or False: With TrueView in-stream video ads, the advertiser pays when someone hovers their cursor over the ad for 5 seconds.
Explanation:

There are two types of TrueView ads: instream and video discovery. With in-stream ads you pay when a viewer watches 30 seconds of your video (or the duration if it’s shorter than 30 seconds) or interacts with your video, whichever comes first.
Your video ad plays before, during, or after other videos. After 5 seconds, the viewer has an option to skip the ad. You pay when a viewer watches 30 seconds of your video (or the duration if it’s shorter than 30 seconds) or interacts with your video, whichever comes first.
