VHS or DVD

Did you know VHS is still having the upperhand in the battle ? Recent numbers show it’s almost even, and it won’t be long before the DVD will take over the VHS. So someone decided that fitness videos are the first to make the switch permanent: next year, no more VHS.
As I’m sure every single one of you has a Billy Blank’s Tae Bo title on the shelf somewhere, my question is, and be honest now, is that VHS or DVD ?
