Where Have the Magazines Gone

When I was a kid, I got most of my SF from magazines.  Amazing, 
Fantastic, Galaxy, Worlds of If, Analog and F&SF provided some great 
stories, book reviews, editorials, a little fandom gossip, and of 
course, Asimov's science columns.  I got busy for a few decades and had 
to slack off on my reading.  Now I'm nearing retirement, and the 
magazines seem to have disappeared.  Are there still any in publication?  
The old digest format seems to have vanished from the news stand.
