If you're talking about earlier dates, ilke 2013, robert w. roche was buying BIG via acorn composite corp, even then. check this out: https://www.sec.gov/Archives/edgar/data/1455206/000114420413064345/xslF345X03/v361280_4.xml
ownership filings are a bit complicated due to acorn composite linking to roche, who is a subset of acorn, so that's why you see some duplicate entries in the filings.
back in january, 2016 RVUE did a deal with roche where they issued stock in an initial "take out purchase" to pay off their debt: http://ir.rvue.com/press-releases/detail/647
then beyond that they issued $1,080,000.00 in "regular purchases" at .013/share for 9 months. this ended last october. https://www.sec.gov/Archives/edgar/data/1455206/000107878216002244/f8k011816_8k.htm
so roche is in it for around $1.3M just on the basis of this 2016 deal.
then add to that whatever stock he bought in the preceding years, some of which i linked at the top of this post, and the 18M shares owned by his family - i think ivue holdings bought around .04/share (don't know for sure), so that's a decent investment which is now way underwater.
all told, this is much more than $720K, more than the $1.3M...
and it's not just roche, go back before the recent roche financing deals, and here's CEO mark pacchini buying at .06, .07, nice big blocks: https://www.sec.gov/Archives/edgar/data/1455206/000121390014000086/xslF345X03/f4020613pacchini_rvue.xml
