On the other hand, if my TV let me type in "CNN" and it came back with
the right channel, that would scale beautifully as long as nobody else
was dumb enough to name their channel CNN.

And if there's CNN 1, CNN 2, CNN 3?
Or CNN Airport, CNN Europe, CNN Latin America.....

Of course, that's as likely to happen as there being
more than one Showtime!!
