What kind of media institution might distribute your media product and why? How will you attract/address your audience?
As well as Youtube, there are plenty of other video uploading sites such as Vimeo which although has less exposure than Youtube, is still quite popular. But the advantages and disadvantages would be the same as Youtube or any other video uploading site.
Speaking of places to upload, don't rule out social networking sites. They are probably some of the most visited websites on the internet and almost everyone has one nowadays, which obviously = BIG TIME EXPOSURE. Sharing it on places like Facebook and Twitter (the most popular social networking sites out there right now) gives you the option to share it with anyone on there. These websites are also free which is always a good thing and you can create your own groups or fanpages to put them onto which lets anyone see them and comment on them. The only problem with this would be that there is alot of competition out there, as there is with almost anything so you would be competing with alot of people all over the world. But there are also other sites, like Myspace, although they aren't as popular. But like I said, some exposure is better than none.
