The Media Hoarder | 1/12/75 commercial breaks from Kojak @TheMediaHoarder | Uploaded December 2023 | Updated October 2024, 1 day ago.
New record for the oldest off-air recording I have (though the absolute oldest playable videotapes I have are the pre-recorded ones from IBM which I've uploaded here.)

Recorded from WBBM in Chicago, split onto 2 30-minute U-Matic tapes so part of the local break was cut out while switching tapes, glad they at least got most of the commercials at the halfway point.

Audio is only in the right channel, likely less than 1% of U-Matic machines at that time were connected to any type of sound system.
