There was a funeral the other day in the Midtown offices of Hachette, the book publisher, to mourn the passing of what it called a “dear friend." Nobody had actually died, except for a piece of technology, the cassette tape. The cassette will grow even rarer now that audio book publishers are dropping them.

Hachette's audio department recently held a “funeral" for cassette tapes. While the cassette was dumped long ago by the music industry, it has lived on among publishers of audio books. Many people prefer cassettes because they make it easy to pick up in the same place where the listener left off, or to rewind in case a certain sentence is missed. For Hachette, however, demand had slowed so much that it released its last book on cassette in June, with “Sail," a novel by James Patterson and Howard Roughan.

The funeral at Hachette -- an office party in the audio-book department -- mirrored the broader demise of cassettes, which gave vinyl a run for its money before being eclipsed by the compact disc. (The CD, too, is in rapid decline, thanks to Internet music stores, but that is a different story.)

Cassettes have limped along for some time, partly because of their usefulness in recording conversations or making a tape of favorite songs, say, for a girlfriend. But sales of portable tape players, which peaked at 18 million in 1994, sank to 480,000 in 2007, according to the Consumer Electronics Association. The group predicts that sales will taper to 86,000 in 2012.

Nowadays, listening to music on cassettes is a dying pastime. None of Billboard's Top 10 albums last week were issued on cassette, though half were released on vinyl, which has been resurging. Last year, only 400,000 music tapes were sold, representing one-tenth of 1 percent of all physical and digital music sales, according to the Recording Industry Association of America. In 1997, the figure was 173 million, and that was when cassettes were already getting a drubbing by CDs. (The iPod wasn't introduced until 2001.)
