Now you can pretend to be a massive corporate #advertiser on the #YouTube homepage, too! Here's an example for #Mastodon: https://www.youtube.com/yt/videomasthead/?video_id=IPSbNdBmWKE&autoplay_fill=1&autoplay_centered=0&autoplay_start=00%3A00&autoplay_duration=00%3A30&ad_title=The%20TOOT!%20revolution&has_ad_desc=1&ad_desc=Welcome%20to%20Mastodon&companion_videos=0&playlist_id=&channel_banner=1&subscribe_button=1&subscriber_count=1&cta_button=1&button_text=Join%20now!&destination_url=https%3A%2F%2Fjoinmastodon.org%2F&layout=material&hash=
As hopefully obvious, I am not actually in favor of advertising. However, I am totally in favor of having fun with the tools given to come up with ridiculous ads that YouTube would never show.
You can put in any video ID. ANY VIDEO. (Yes, I restrained from making my original link a Rickroll.)
