That list seems theoretical not realistic. I mean except us geeks, who's heard of Cisco? And who's heard of GE outside of the US?
I would easily place Apple in the top 5.
Coca Cola
McDonalds
Microsoft
Apple
I thought EXACTLY the same thing when I saw Cisco on the list. Cisco just flat out shouldn't be in the top 100 on anybody's list. Not that Cisco is a bad company, but they don't make products that make it into consumer households (well... they do own Linksys now, but why isn't Linksys on the list?). If you're not in the IT field, you probably wouldn't have any exposure to them.
I suspect the study involved too many people in certain careers, age groups, or countries.
If you ask someone in Guatemala what Coca Cola is, they've heard of it and they know what it is. Ask them what "H&M" is and people in MOST OF THE WORLD haven't the foggiest. Many of these top-100's just shouldn't be there.
