How Companies Can Use RSS Feeds

http://www.zdnet.com/blog/emergingtech/rss-for-companies/347

I had no luck finding articles on how specifically each company implements and uses RSS/Atom feeds, but I found this article that has a few details on how they can be used in a broad manner. The three things that stood out were the following:

• Using RSS Feeders may possibly replace the current E-Mail system(s) in place.
• Provide Information and Updates to Customers and Employees.
• Using it to help the business in a more efficient manner by being specific in news delivered.

Granted, this article was written in 7 years prior, but I think it gives a general look into how exactly it was/is being used.
