The Chicago Tribune is founded. The original press run consisted of 400 copies printed on a hand press.
The Tribune erects its first building, a four-story structure at Dearborn and Madison Streets. In October 1871, when the Great Chicago Fire raged through the city, the wooden building was destroyed, as was much of the city. The Tribune reappeared two days later with an editorial declaring, "Chicago Shall Rise Again." The newspaper's editor and part-owner, Joseph Medill, was elected mayor and led the city's reconstruction. A native Ohioan who acquired an interest in the Tribune in 1855, Medill gained full control of the newspaper in 1874 and guided it until his death in 1899.
Medill's two grandsons, Robert R. McCormick and Joseph Medill Patterson, assume leadership of the company. Also, the Chicago Tribune's first newsprint mill opens in Thorold, Ontario. The mill marked the beginnings of the Canadian newsprint producer later known as QUNO, in which Tribune held an investment interest until 1995.
WGN(AM) Chicago signs on, its call letters reflecting the Tribune's slogan, "World's Greatest Newspaper." It was first to broadcast the World Series, the Indianapolis 500 and the Kentucky Derby and broke new ground by introducing microphones in the courtroom during the 1925 Scopes "monkey trial" in Tennessee.
Construction completes its new headquarters, Tribune Tower, one of Chicago's first skyscrapers. Tribune Tower's neo-Gothic design was chosen from 263 entries in a $100,000 international competition. The 36-story building is a Chicago landmark and perhaps best-known for the many historic stones and artifacts from other famous buildings embedded in its limestone exterior.
Chicago Tribune-New York News Syndicate is formed. Its successor, Tribune Media Services, offers hundreds of different products, including classic to cutting-edge comic strips, columns from top commentators, and other specialty features products. In addition, the TMS Entertainment Products Group now collects and distributes television, movie and Internet programming data.
- WGN-TV Chicago signs on, followed by WPIX(TV) New York. These stations, now affiliates of The WB Television Network, became the foundation for Tribune Television, today one of the country's largest TV groups.
- Tribune publishes its famously wrong "Dewey Defeats Truman" headline on Nov. 3. Surprisingly, the newspaper did not possess a copy until a Tribune
executive, Owen Youngman, bought one off of e-Bay in 1998.
A century of family leadership, starting with Joseph Medill in 1855, ends with the passing of Col. Robert R. McCormick, the longtime editor and publisher of the Chicago Tribune. The McCormick Tribune Foundation was established as a charitable trust upon McCormick's death and now claims assets of more than $2 billion and annual giving of $100 million.
