The 3 inch or 8cm compact disc (also branded as CD3 in the US) was an attempt to sell CD singles and EPs at a lower price point that would be distinguishable in size from 5" (12cm) CD albums, similar to the differences between 12" and 7" records. The first titles (mostly promotional) were released in 1987. In the USA, indie labels such as SST, A&M and Ryko were pioneers of the new format. Virgin was heavy into the format in the UK. By the early 1990s, the format was dead in the US and in Europe. Music CD3s saw a brief revival around 2001-2004 when 3 inch CD-R and slimline miniCD jewel cases hit the market, and then died a second time. In Japan, the format was more successful, and 3 inch CD singles were available from 1988 to around 2003-2004. They are still occasionally released as novelty items. I bought a few of these in my CDs when they were first released, starting with the Don't Let's Stop EP by They Might Be Giants, but about a decade ago started buying more of them online, which grew into this collection. Many date from the late 80s to early 90s time frame that I was DJ at a college radio station and was into the early Alternative Rock of the time, so there are many with music that I really enjoy. I recently bought another batch of them via eBay, and also a tiny personal CD player for the 3 inch discs (see My "new" kawaii miniCD player: Aiwa XP-Z3C). My purpose in this thread is three-fold. 1) Post a bunch of photos of my collection of 3 inch CDs, and show them off. I have over 250 of them that I have bought over the years. 2) Discuss reasons why the small format CDs did not do so well in the marketplace. They fared best in Japan, so I have been considering some differences in how they were sold and marketed in Japan than in the rest of the world. I'm guessing the "kawaii" cuteness factor had something to do with the success in Japan. In looking through my collection this past week, I've also noted two trends: A) Most Japanese 3" CDs came in a standardized snap-pack. This made merchandising and selling the format easier (I've even seen reports of vending machines there) than in the US and Europe, where there was never a standard size for the packaging. B) US record labels such as MCA and Rhino flooded the market with oldies reissues in the CD3 format. Perhaps if the format would have been associated more strongly with new releases targeted at younger buyers as it was in Japan, it would have fared better. 3) Get some conversation going about this "obsolete" format that remains compatible will almost all CD players. Some overall photos of the collection: This shoebox holds some extra jewel cases, spare adapter rings, and such, as well as some sealed and open long boxes, the items in plastic on the left. I got these boxes on clearance from Bags Unlimited, and have a few more still unfolded for when the collection grows. The box on the left has the Japanese snap packs, with the discs stored in jewel cases too, while the other four contain the CDs that came in the 3" square cardboard covers. The cover and the CD inside a jewel case are kept in a polyprop sealed sleeve, also from Bags Unlimited. The ones that came in large jewel cases or 5" square cardboard covers are in these three plastic boxes. Also stored here are the Capital soft plastic cases safely stored in jewel case sized "calendar cases" that I also got from Bags Unlimited on clearance. All of the red cases in the box on the left are these, holding a full set of the Beatles' singles on 3" CDs.
