On TV IFs I think it started to become common in the mid-late 50s. It never was standard on TV tuners. Many brands simply had a couple of solder stakes to solder the coax to the tuner and that was a common cost saving measure up until the combined tuner/IF systems of the solid state era.
The RCA jack as a standard connector for consumer coax applications (primarily audio) dates back to pre-WWII IIRC.
