Chris, what a great cultural artifact! I'm pasting here, and will also put in the "Court Cases" section of the links page, links to the two Supreme Court decisions that legalized birth control across the country.
Griswold v. Connecticut, in 1965, was the first, and that one is also the one in which the "right to privacy" that supports Roe v. Wade is first really drawn out. (I've written before about how that was a weak decision in some ways because the Constitution doesn't contain such a clearly stated "right to privacy" but instead Justice Douglas found that there are "penumbras" and "emanations" that form from the rights guaranteed in the Bill of Rights to "guarentee zones of privacy."
The second, Eisenstadt v. Baird , extended the right to contraception to unmarried people in 1972. The law in question in the Eisenstadt v. Baird case was a Massachusetts law that made it a felony to distribute contraceptives to ummarried people!
...because public space really matters!
