In a similar fashion to tweeting your video to celebrities, you can also send your video around to bloggers and popular blog sites, and influencers in your field. This will enable your content to reach a large amount of people with shared interests - plus it can help open the door to a possible collaboration with other people in your market.
You should also customize who you send it to. For example, if your video is about your marketing brand, send it to marketing influencers and blog sites. This way, you can create a buzz within the community you're looking for brand recognition in.
