Shopping over the smartphone helped power HSN's first-quarter earnings, CEO Mindy Grossman told CNBC Wednesday.
The company, which runs a television shopping channel and companion websites, reported earnings of $26.2 million, or 44 cents a share, blowing by average analyst expectations of 37 cents a share.
"It's really been about growth across all our digital platforms," Grossman told Squawk on the Street. "Mobile has been a key driver. We did over 50 percent of all the mobile sales in 2011 just in the first quarter of 2012...It bodes well for the investments we made in that experience."
