What is the best way to advertise online (towards medical professionals) with a $100 per week budget?

Viral marketing would be applied to some of the following processes:

1. Sending out a PDF file to a list of email subscribers that has links to your web site(s) in them and the content is so good and compelling, that those who receive them, instantly forward them to friends.

2. Videos: Creating and uploading videos regarding a particular product/services to sites like Youtube.com and Viddler.com is another way to 'spread the word' via those who watch it.

3. Creating a toolbar and then distributing that to users.The toolbar would then of course include links to your favorite website(s).

Basically, Viral promotions can take the form of video clips, interactive Flash games, advergames, ebooks, brandable software, images, or even text messages in order to spread information about a given product or service.

For instance, let's assume you've setup an account over on Twitter and have a few 'followers'. You could make a small announcement to your followers about a new product/service/website. Your followers like it so much, they do you a favor by doing 'word of mouth advertisign' for you...Ever see a commercial for Myspace? What about Facebook? I haven't! Yet, these are two of the largest 'social networks' on the internet. How did they get there? Viral Marketing!
