The website Wedding Crunchers displays keyword trends from 1981 through 2013 in New York Times wedding announcements in Google nGram style. For example, back during the first Reagan administration, more NYT wedding notifications mentioned "Republican" than "Democrat" or "Democratic." Recently, however, Democrats have opened up a 3 to 1 lead.
RapGenius has an interesting analysis with lots of graphs.
