Thank you, Jan. Given the strategic changes we have made to the business, our financial reporting has changed significantly. Effective April 22, 2016, we no longer consolidate the results of DSIT, which has the effect of reducing our reported revenue to just those of our OmniMetrix business from that day forward, and it also impacts the comparability to prior period results.
Focusing first on OmniMetrix. Our revenues grew 10% to $761,000 in the second quarter after giving effect to a negative revenue adjustment of $130,000 with respect to a previous understatement of deferred revenue. The required adjustment was made following an in-depth analysis by members of our new accounting staff at OmniMetrix, which was brought on to strengthen that function. Excluding the adjustment, OmniMetrix second quarter revenue would have increased 29% to $891,000 and first half revenue would have increased 27% to approximately $1.7 million. The revenue improvement is driven by overall business strength, but specifically by increased hardware sales. Importantly, increased hardware sales directly feed into our ongoing maintenance revenue base, supporting a stable and growing revenue base. We have indicated on prior calls that we expect 25% annualized growth in this business, and that continues to be an achievable target.
Turning to DSIT. We previously mentioned that DSIT is no longer being consolidated in Acorn's financial results following the April 2016 of a portion of our holdings, which reduced Acorn's ownership in DSIT to below 50%. Nonetheless, DSIT is the largest asset on Acorn's balance sheet and is therefore very important -- and is very important to Acorn.
So let's look at DSIT's overall performance, recognizing that Acorn now owns 41.2% stake. On an enterprise basis, DSIT achieved significant growth in the second quarter, with revenues increasing 16% to $3.9 million from $3.4 million in the second quarter of 2015. For the 6 months ended June 30, 2016, revenue grew approximately 22% to $7.9 million from $6.5 million in 2015. The increases were principally due to contributions from a $15.4 million project DSIT secured in the first quarter of 2015.
Acorn consolidated share of DSIT's operating income was $99,000 for the first half of 2016 versus a loss of $71,000 in the first half of 2016 -- I'm sorry, that was a loss of $71,000 in the first half of 2015. In addition, Acorn reported income of $25,000 in the income statement line share of income in DSIT for the period from April 22, 2016 through the end of June 2016. Acorn also recorded a $3.5 million gain on the sale of DSIT, which was reflected in both the second quarter and the first 6 months of 2016.
For the second quarter of 2016, Acorn reported net income attributable to Acorn shareholders of $2.4 million or $0.09 per diluted share, of which $0.10 per share was from continuing operations and a loss of $0.01 per share from discontinued operations. This was compared to a $3.1 million net loss in the second quarter of 2015, which was $0.12 per share and included a net loss of $0.05 per share from continuing operations. For the 6 months ended June 30, 2016, we reported a net loss of $539,000 or $0.02 per share, which was comprised of net income of $0.04 per share from continuing operations and a loss of $0.06 per share from discontinued operations. This compares to a net loss of $5.9 million or $0.22 per share in the comparable period in 2015. The $0.22 loss per share in 2015 was comprised of losses of $0.11 each in both continuing and discontinued operations.
Looking forward, our third quarter results will reflect solely our OmniMetrix business on the revenue line. As a result, third quarter and year-to-date revenues will be substantially reduced relative to prior year period.
Blended gross margin in OmniMetrix is expected to be over 50%, including gross margins in the recurring monitoring revenue stream, which are over 80%. From a cost standpoint, normalized corporate, general and administrative overhead, excluding special costs such as attorney and other fees related to strategic initiatives, have been reduced to below $350,000 per quarter after averaging over $700,000 per quarter, excluding noncash stock compensation expense, over the last few years. And we continue to search for and identify further reductions. It will take some time, but continued progress on the cost side, combined with growth in the business, should lead to better operating performance for Acorn, with the ultimate goal of profitability as quickly as we can manage and accelerated via acquisition as possible.
And with that, operator, let's open the call for investor questions.
