'Mad Men' Tackles Pop Culture History: Other Major Events That Happened In 1966 And 1967

"Mad Men" Season 5 has been chock-full of headline-making events from the year 1966. They've covered the race riots across the country, the Richard Speck murders in Chicago from July 1966, the shootings at the University of Texas at Austin in August 1966 and the height of Rolling Stones mania as they topped the U.S. and U.K. charts. (We're still waiting for a mention of Rita Moreno ... )

And after this week's trippy episode of "Mad Men," we can imagine what Roger Sterling would have to say about the fact that it was in September 1966 that Timothy Leary founded the League of Spiritual Discovery, a religion based on LSD, which was made illegal the following month.

We also know that 1966 was the year that mini-skirts were really in fashion (Zou Bisou Bisou!), color TVs became popular, Jacqueline Susann's first novel "Valley of the Dolls" was published and all cigarette packets in the United States had to start carrying the health warning "Caution! Cigarette smoking may be hazardous to your health."

But what other pop culture events from the end of 1966 through 1967 might "Mad Men" incorporate this season? Here are some major landmarks we could see getting a shout-out on the show.
