Viral marketing, a form of online marketing, has become important for businesses to deliver social and digital content which encourages sharing between users. File Sync and Sharing Vendors, like PanTerra Networks, a provider of cloud-based fully managed and self-managed unified IT service solutions for mid-market enterprises (MME), adds Unified Communications (UC) to the mix via the cloud (UC as a Service), which gives functionality to store, sync and share content. Think of it as Skype meets Box, explains Arthur Chang, CEO of PanTerra Networks.
