    they didn't when they were new, but as someone else has already added, the large hole was to enable them to be played on a jukebox. I can remember buying ex jukebox records in my youth (I am now 53) and having to buy the little plastic adaptors to be able to play them on my record player at home. I probably still have some in my collection which I am shortly going to transfer to my Ipod via my computer!!

    The tolerance of the mechanized equipment in juke boxes in the early fifties neccesitated the larger hole format to insure a record found its way into place on the enlarged spindle. The small hole format proved too unreliable for the 78's on the earlier juke boxes of the thirties.

    I don't know why, but they had a different sized spindle on the turntable/player. The spindles had a little lever that would let you stack several records and as they finished playing a new one would drop onto the turntable. The 45's had a larger spindle. I used to think it was for stability, but maybe not.

    They had the same size hole, but the centre was designed to pop out so that they would fit certain jukeboxes. http://tinyurl.com/3a2rha

    Very simple- they had a bigger hole so you could hold them with your thumb or finger without touching the grooves. 10 and 12 inch records were too big for that
    to begin with. Remember that jukeboxes existed before the big holes, so they had nothing to do with it.
