Just from almost a year of watching it trade and be taken down by the MMs. MANY people held many shares back in Jun/Jul '11, check IHs historical trade/PPS feature and go back to last summer when DUTV was in the 30-50s, if I recall! DUTV imo was a victim of some shannigans being played out in at least three other pinkies. Something broke loose yesterday. One PR in the last 6-9 mos and volume went off the charts and PPS flew. The technology is great, and haven't seen something similar without buffering etc.
Could be a lot more going on behind the scenes than just a PR being released.
All the best,
