I do not understand those "separate" products at all

NotifiAIR, NotifiLINKS, NotifiWEB, NotifiADS, NotifiLIVE

I thought they're all one product with different names? They're not separate products. Am I mistaken? Can someone provide an example? Because I have yet to find one. Or maybe, they're not realized products at all?

For instance, notifiCRM allows you to use interactive video in any way. And those interactive videos are walk-outs: notifiAIR. Those videos can contain interactive buttons to direct you to a website or document, etc: notifiLINKS. notifiWEB: customers can have interactivity appear in their website? etc., etc.

I just don't understand how they're all interrelated, how they're different, how one can survive without the other, etc.
