What's up with single letter domains?

[nsood3]

It's a slow day, so here's a fairly pointless topic:
Just out of curiosity, I went to www.a.com to see if anything was there. There wasn't. There wasn't anything at www.b.com either, or any of the single letter dot coms. Until I went to www.x.com, which forwarded me to paypal, and then www.z.com, which gave me a certificate warning, which I ignored, and it ended up taking me to the actual z.com, which turns out to be owned by Nissan.

So my question is: what's up with that? Why isn't anyone using single letter dot com names? It seems like "a.com" or i.com or u.com would be a pretty unbeatable domain name.

I would've assumed that they aren't allowed to be registered, but then there's Paypal and Nissan..

I was not aware of any single letter domains. Then you came along and informed me. Even I have no idea, why some one did not try them yet?

They are banned :|

ICANN doesnt want them to be sold to anyone..
God knows why..

:P

x.com was a service similar to PayPal , but PP bought them out..

well as for my knowledge is conccerned this type of single domains were availble initially but not now. All, of the single letter domains have been banned now.

I have not aware of the fact regarding single letter domain names, your information is interesting, But I could not understand why they banned such unique one letter names, I think anyone can buy this names with great value
