The agency I work for has put together a series of podcasts to add our two cents about MARCOMM. You can listen to them here. Mine's entitled "PR's Role in Enhancing Marketing Efforts" (OK, so not the most creative title), but it gives an overview of what I believe to be some of the strong benefits of executing a strategic public relations campaign in conjunction with other marketing, digital and advertising efforts.
Oh, and I was still getting over some awful flu/cold/stomach bug when this was taped so I swear I don't normally sound like that!
Let me know what you think!
