An early form of polling, started at about WWI, invovled mailing a huge number of polls out to "randomly" selected people, who would then decide if they wanted to respond or not. These were done by magazines. Ever ballot also had a card to subscribe to the magazine.
They were wildly popular and surprisingly accurate.
Then, in 1936, it blew up on the Literary Digest when they chose their sample primarily from a list of automobile owners and private telephone owners. This heavily sampled teh wealthy, a demographic that heavily opposed Roosevelt.
