You an hallerb can discuss the public relations aspects.

I think the question is interesting from an almost philosophical
viewpoint; we don't often run into things where the speed of light
enters into the equation of what "now" and "live" are.

It's the first indication we ever had that light had a finite speed,
incidentally - complex calculations had been done to say when Jupiter's
moons should transit or be occulted, - and it was found that they worked
fine at conjunction but were reliably minutes off at opposition, or
similar...

The phenomenon is worth more than a footnote of interest :-)
