Puzzling why broadband users are more aware of DTV changes than other groups

As you can read in this grab from online marketing news and research site eMarketer's analysis of the demographics of households aware of the nation's transition to digital tv, broadband Internet customers seem to be more aware of what's going down than even digital cable subscribers are.

Quickest of backgrounders for those not in the loop: On Feb. 17, 2009,  all US broadcasters must stop analog broadcasting and complete the switch to all-digital signals.

That's a bit surprising, considering that the presumption would be that digital cable subscribers would care more about tv technology consumption requirements than broadband Internet subscribers might. 

The same broadband Internet subscribers who, to a significant extent, have forsaken tv watching for Internet multimedia. 

My opinion-facilitating neuron paths have yet to kick in on this one.

Readers, what do you think?
