They do, and sometimes those Africa-oriented broadcasts do make it into the US, but even on the east coast it can be a dreadful signal. The Beeb was a big loss when they stopped offering English to North America, but since then they've become available in so many other ways — online, on XM/Sirius, via many HD subchannels of NPR outlets — that I don't miss it quite as much as I do some others like Australia.
Australia was a great companion of mine when I was working my first job right out of high school. I had the luxury of basically being an office gopher in a building all to myself, so I'd bring dad's shortwave radio every day and listen to their programming beamed from Sackville. It was a massive signal back then up and down the east coast! (I certainly got the occasional odd look from the other co-workers when they dropped into my building, though.)
As crainbebo noted, they're gone. Only CFRX remains, and its 1 kW signal isn't the easiest to hear right now with conditions being so poor. At least not down here in Alabama. It is still odd to hear it, though, since it's just a typical commercial AM news/talk type station with that broadcast sound that is lacking on shortwave for the most part.

It's worth noting that for all the big boys who've abandoned shortwave, there are a few smaller players still surprisingly hanging in there. Radio Nacional Amazonia from Brazil has been back for a while now after a major transmitter plant fire took them off a while back. Normally something like that should spell the end of shortwave transmissions but they're on 6180 and 11780 with a lot of programming. Ditto XEPPM in Mexico City, which still plays a lot of interesting music. They had a transmitter refurb not too long ago, too. The Solomon Islands are still on (at least I think they are?) after China basically gave them a new TX. And a station called Radio Montaña in Colombia recently signed on as well. Like Radio Clube do Para in Brazil, they're kind of a tough catch with less than 5 kW but it's there if you get lucky.
Oh and Argentina, Slovakia and R. Prague are still available via WRMI. I've heard a lot of interesting music from them in the past few years.
