WTBS coming up next (circa 1983) 2018 HD version
Back in the days of analog TV and SuperStationWTBS, I designed these 20 second promos that used a Chyron IV, an ADDA still store, a Grass Valley 300 switcher, and lots of button-pushing on the director's part to create one-offs. If they were done in HD, they'd look something like this.
Someone uploaded an off-air recording of the original version (thanks!) here: • TBS COMING UP NEXT! (1983)
