Cant go by individual users on the thread here as a statement for the longevity and sustainability of ota. Remember this site is dedicated to those of us who are hobbyists and in many cases fanatics for television and all you have to do is look around at some threads or a picture gallery to see who has 4, 5, 6, 7, or more satellite dishes and service coming from E, D, cable, ota, and fios.
Drive through your neighborhood and look at how many antenna's you see then think back to 10 - 15 years ago. Anyone thats involved with installing for cable or satellite will also know the decline of ota use in the households across the country as an installer generaly gets into many rooms of a house including attics and on roofs.
Im not dipsuting that people use ota still but with cable and satellite and now fios offering way more channels than an antenna even many of the die hard hold outs and penny pinchers are on these services now.
