This question concerns very recent history, I apologize if it is too recent. I recently saw an episode of the British comedy series Keeping Up Appearances from the early 1990's. In it, one of the characters can be seen reading a magazine called "Classic CD". Apparently this magazine is no longer in existence, and I became curious as to what type of magazine this was, when it started, and when and why it ceased to exist.
Classic CD was a monthly magazine which targeted the classical music market.
The first issue had a cover date of May 1990, so it's not surprising that it featured in a BBC sit-com from the 1990s.
I think the final issue had a cover date of August 2000 (issue number 127). I've seen copies of the magazine come up on eBay (often complete with the cover CD) quite frequently.
I wrote for Classic CD in its earliest years.
I suspect that the reasons for its disappearance included the success of BBC Music Magazine (launched slightly later) and the modernisation of The Gramophone, which were surely its chief competitors.
Also, its publisher Future Publishing underwent some ownership changes and an IPO around the time it closed, so it's very possible that it simply didn't fit into their business plan. Future tended to have multiple magazines in subject groups, but Classic CD didn't really fit into any of them.
It was a great magazine, though.
Somebody mentioned there not being online equivalents. That's not quite true - there are some, such as ClassicalSource.com. But it's fair to say they don't have a very high profile.
