What is New Age Buddhism?

I've noticed that we have a tag on the site for New Age Buddhism which has a couple of questions associated with it (one more now I've asked this!). What is New Age Buddhism though. Can anyone give a reasonable concise definition of it, maybe point to some links for more detail and give a few teachers that follow or expound this line of Buddhism. Does it have anything that uniquely differentiates it from other forms of Buddhism. Or it is a not genuine concept at all?
