Mobile sales make up a growing share of digital sales at HSN Inc., and digital accounted for more than half of all sales for the first time last year, the TV, web and mobile retailer reported this week.

“We have made progress in certain key areas, including optimizing our sophisticated digital platforms,” CEO Mindy Grossman says. “For the first time, HSNi’s digital penetration exceeded half our sales at 52%, with digital reaching nearly $2 billion in annual sales. Additionally, mobile now represents nearly 40% of total digital sales.”

Grossman attributed a slight Q4 sales decline to heavy price discounting, according to a transcript of HSN’s year-end earnings call from SeekingAlpha.com.
