Tactics:
–Add links to videos and relevant material on your site and distribute to these selected channels.
–Promote your content available via RSS feeds.

–Industry Sites: Don’t spam. Participate in conversations and when appropriate add links to your content.

–Other Bloggers: Establish a meaningful relationship with them and it will really work for you.  This will test your P2P networking skills.  Make them look good!

–Social networks:
In general all information you release should reflect on your social media profiles. Status updates on Facebook, Twitter and other networks are the hooks that bring people to your content and give them the opportunity to share it with their friends. If you add content more than once a day then you should experiment with the frequency of updates so that followers wouldn’t perceive you as spammy.

–News sites/Bookmarking:
StumbleUpon and Digg are probably most important of those but your niche might have other special news sites.
