- after the video is over, but before the end cards/credits
- same as above, but with a short five second teaser at the beginning
- in the middle of the video, surrounded by a transition or two (eg ‘we’ll be right back’)
- at the very beginning of the video
- in the middle of the video with no warning whatsoever
- after the intro/cold open, but before the main content of the video
- after the intro and a bit of introductory spiel about what will happen in the video, with almost no warning whatsoever
caveat: i will still watch your ad plug if it is dumb/funny enough (brutalmoose does a good job of this)
