Cool down I really didn't mean to cause an issue. Sorry I misread your post. The TV in the pic is near an edge and tempered glass is strong. They could have either made a dado or used shelf brackets. I've stacked a lot of dishes on tempered glass with no issues, though the span in the pic is larger than moat cabinets . Newer tvs do not weigh very much and I suspect glass would hold many units.
Sorry you took my earlier post so hard.
Edit: I just looked at the photo on a desktop and it appears that there are supports going from front to back to hold the glass. At .5 inches the glass will support quite a bit. It is not solely supported by the front, IMO.
