Has anyone else noticed that the Prudential commercial
on TV is sending SMS instead of SOS?

I recall that decades ago, there was an FCC prohibition against the
inclusion of the SOS pro-signal in commercial radio and television
broadcasts. You weren't supposed to ever transmit this signal unless
you were actually in distress.

TV shows would either just *refer* to their being an SOS in progress,
or would transit some other Morse code signal as a substitute, or
both. I remember one Star Trek episode in which the substitute signal
was actually a very-low-speed FSK signal (high and low tones, about an
octave apart).

I don't know whether the legal prohibition against transmitting SOS on
commercial radio/TV still exists today, or whether it was dropped
during the big deregulation.
