'How' and 'Where' you show your video content has become part of the brief.
It makes a difference in terms of the audiences and potential audiences that can be reached and the way in the which your content could, if you wish, be reversionsed and used in different ways (hopefully, under the right Creative Commons) with links back to you.
On your website, whether on the intranet or for exeternal viewing where it can be shared and discussed.
It can also go out as a channel in its own right. At the broadcast end I recently saw what some of the content going out on Channel Flip. Today you can have your own channel. If you have appeal to an audience and can attract enough viewers advertisers will sponsor your content.
Elearning has become far easier to mange and distribute with platfroms such as present.me for video, but also specialist mobile elearning platforms like GoMo from elearning specialists Epic.
The right content may be used in qualifications too.
Put on YouTube your content can be embedded within other people's content while you can take advantage of detailed analytics, not least viewing behaviours.
