What's in a name? A Digital Asset Management System and Media Asset Management System are alike, the differences are subtle.
In fact we reckon that today there is almost no difference at all - other than a name and Media Asset Management software vendors are typically a little more focused on broadcast or broadcast quality video.
This means the average file size of Assets in a MAM are significantly larger, and as a consequence some of the features and processes differ.
Furthermore, most DAMs are used to manage predominantly images and video. They are sold to marketing teams, and some cases to the IT department, of brand name companies. While Media Asset Management Systems are typically sold to Media companies. So while the technical differences are blurry. Perhaps it's the intended customer profile that best differentiates them.
Of course with the advent of social media and streaming to a myriad of devices, the general quality and size of all video has risen, and so MAM and DAM software capability is much close today than in the past.
In reality MAM and DAM are more or less the same thing and you could use either moniker interchangeably to describe Media Asset Management or Digital Asset Management software.
