Before there were blogs and the web, I used to be an avid reader of magazines, subscribing to as many as thirteen in the early 1990s, many of them in computer programming, particularly the less popular, more technical magazines that I could not read in the libraries.
Eric Sink noted two years ago that computer magazines were dying, reflecting a larger trend in which nearly all paper media is declining amidst the technology boom.
Dr. Dobbs Journal, one of my early subscriptions, appears to be the latest developer magazine to disappear. I subscribed to about three different magazines on C/C++ programming including C++ Report and C/C++ User Journal, but it doesn't appear that any of them are still around. Byte went out of print fairly early, and Software Development magazine disappeared.
Microsoft System Journal still survives in the name of MSDN magazine from a merger with MIND magazine, but as Microsoft's official magazine for announcing new technologies, its future is guaranteed.
