The earlist commercially available recording, from about the 1880's until World War I, were wax cylinders about 1/4" in diameter and 6-8" in length.
There were disks in the early part of the 20th Century,but the disk did not really take over until the time of W.W.I., simply because your early record players were hand operated(a crank) and you could not get a consistent speed, which was not as much of a problem on the cylinders.
During the 1910's and early 1920's, with the advent of the electric record players (and thusly the ability to have a constant speed), your first main format came out, the 78 R.P.M. record, which from the teens to the fifties was the standard for recorded music.
In fact, the term "album" comes from the 78 RPM record,when collections of songs by an artist, or a long classical/operatic work which requiered 5 or 6 78's,would be sold in a book,with the required number of sleeves for the disks bound in.
In 1949 began the war of the speeds when Columbia(CBS,today Sony), brought out the 33 1/3 RPM Long Playing record, and to counter it,RCA (now BMG) brought out the 45 RPM single, which did kill off the 78(though both were issued until at least 1957).
Also during this time, primarily IMO due to the fact that many record players did not play both speeds (i.e. 33 1/3 and 45 RPM), you had the Extended Play 45,which would usually have 4-6 songs from the artist' current LP issue. 2-3 EP's would comprise an LP. Also in this time was the short lived 16 RPM LP,used mainly for transcriptions of classical cooncert and radio shows. Also reel-to-reel tapes came out then,and they lasted till roughly 1972.
Tape grew in the 1960's with the 4-Track cartridge(c. 1965-c. 1971),the 8-Track cartridge (c. 1965-1988),and in 1966 the cassette, as well as the very short lived Playtape(67-69), and your early flexidiscs(Pocket Discs,also roughly 65-69).
The situation stayed like this until the 1982 introduction of the Compact Disc, and by the late 80s you almost could not find LPs or 45s.
There were attempts at DAT(Digital Audio tape), which was marketed in the USA as DCC(Digital Compact Cassette), but the format never caught on. There were also 3" CDs, which were to replace 45s, but again they didn't really catch on.
I hope you find this of interest.

Tim, I'd be very very interested in your opinion on an article I wrote about stereo, mono,CD and DVD quality, things like that. Would you mind reading it? Take my link below to the 'Reading Room" and find the "You Can't Do That" article. And anyone else that'd like to read it, please do!!

Indeed that's an interesting bunch of information, Tim. Thanks for posting it and for sharing your knowledge with us... http://www.beatlelinks.net/ubb/smilies/images/icons/smile.gif Being you the expert you seem to be in music formats, I see here an opportunity to ask you a couple of questions that have to do with that subject.

If you look at the Paul McCartney discography, being him the most prolific of the four during the solo years (a very extensive one can be found on http://macca.has.it), you will find lots of formats for his singles, specially throughout the 80's.

I would like you to expand that particular subject: the main differences between 7" and 12" singles (besides de length, of course http://www.beatlelinks.net/ubb/smilies/images/icons/wink.gif) and the average 45 RPM singles; and what are the CD-5s and CD-3s and what are their differences with the average CDs.

Thank you again. http://www.beatlelinks.net/ubb/smilies/images/icons/smile.gif

The 12-inch singles would usually play at 33(like an LP), but would usually have 3 songs (e.g. on the Ebony and Ivory 12-inch side 1 was E&I, side 2 was the flip with a bonus version of E&I that was just Paul with no Stevie Wonder).

CD-3 was a 3-inch CD (a normal CD is 5 inches in diameter)with 2 songs.
