ChyronHego Corp. Friday posted a 57 percent year-over-year increase in first quarter revenues to $12.6 million, but a wider net loss of $3.2 million, or 10 cents per diluted share, versus $900,000, or 5 cents per diluted share, in 2013.

The growth in revenue was largely attributed to the merger between Long Island-based Chyron Corp. and Sweden's Hego AB that was completed in May 2013.
