What was going on in chicago in the late 60s and early 70s?

Things were going along as they did in the 50s but tv was more influential. It was influential in a few ways. 

Music was a mixed bag with a couple stations playing swing and polkas and a couple playing gospel and blues while rock and roll was going strong...hard rock, psychedelic rock, folk rock, hill billy rock, Detroit rock, Philadelphia rock, and even some home grown Chicago rockers. 

TV brought us the news. People became news obssessed...men walking on the Moon, Political assassinations, the never ending war in Vietnam, racial turmoil, the Beatles, Mayor Daley never ending terms, political unrest in :incoln and Grant Parks while the poilice bash in heads while theworld watches...on live tv.
