Until last year it was possible to create a display network ad on Google Adwords (now Google Ads) that featured just a video and was paid for on a pay-per-click basis. It was one of the ad types available in the "ad gallery" that was available at that time. These kinds of ads (along with the rest of the ad gallery) appear to have been phased out around July - August 2018.
Does anyone know if there is an equivalent way to create these kind of ads today?
Display network ads now seem to be required to be "responsive display ads" which can feature videos as an optional item, but it seems to be up to Google to decide whether or not the video is actually shown. In most cases they only seem to display the mandatory static images, not the video. Performance of these kind of ads is therefore much closer in aggregate to static banners rather than video ads.
