Surviving telecasts

For all of the League Championship Series telecasts spanning from 1969 to 1975, only Game 2 of the 1972 American League Championship Series (Oakland vs. Detroit) is known to exist. However, the copy on the trade circuit of Game 2 of the 1972 ALCS is missing the Bert Campaneris–Lerrin LaGrow brawl. There are some instances where the only brief glimpse of telecast footage of an early LCS game can be seen in a surviving newscast from that night. For instance, the last out of the 1973 National League Championship Series as described by Jim Simpson was played on that night's NBC Nightly News, but other than that, the entire game is gone. On the day the New York Mets and Baltimore Orioles wrapped up their respective League Championship Series in 1969, a feature story on the CBS Evening News showed telecast clips of the ALCS game (there's no original sound, just voiceover narration). This is all that likely remains of anything from that third game of the Orioles–Twins series. Simpson's call of the injury of Reggie Jackson during Game 5 of the 1972 ALCS is heard on the 1972 World Series film, as well as Curt Gowdy's call of the home run by Johnny Bench in Game 5 of the 1972 NLCS as well as Bob Moose throwing a wild pitch to pinch-hitter Hal McRae scoring George Foster with the winning run.

Local television

As previously mentioned, from 1969 until 1983, the Major League Baseball television contract allowed a local TV station in the market of each competing team to also carry the LCS games.

1970s

National radio

From 1969 to 1975, there was no official national radio network coverage of the League Championship Series. NBC only had the national radio rights to the All-Star Game and World Series during this period. Instead, national coverage was provided via broadcasts syndicated over ad hoc networks.
