Disney's pilot MovieBeam setups used the Dotcast data delivery system, which 
puts digital data on top of NTSC analog signals.

Disney's business model was to install a Dotcast modulator at every PBS 
affiliate.  We had a couple of surveys to determine what equipment they 
would need to provide for our particular transmitter.

Disney must have finally found out that A) their service was way overpriced 
for the number of movies they could deliver (espeically when compared to a 
DVD service like NetFlix), and B) maybe Congress and the FCC were serious 
after all about eventually shutting down NTSC.

I opened up a Square Shooter last year, and it is basically a printed 
circuit antenna.  It's only forte is an extremely high front to back ratio 
similar to a Silver Sensor, which of course minimizes the amount of 
multipath an ATSC receiver has to deal with.  As the multipath load is 
reduced, the lower the S/N required to demod ATSC.
