We share new stories within multiple sales and marketing Webex spaces, and also provide social links to these audiences to make it easy to share the story externally. In addition to what's shared above, perhaps send a regular email update to sales leaders with these new stories, and present them on sales calls. Given your amazing success in capturing stories every other week, you can remind the sales teams about these (they have short term memory, I swear) and where to find them, assuming you have a library or webpage or sales folder/tool where they are all stored. Remaining top of mind is key!
