Nike Inc’s Web sales are growing fast, the firm's chief executive Mark Parker said Saturday.

We've seen a fairly dramatic increase in online sales, Parker said in Davos, Switzerland at the World Economic Forum, according to Reuters.

The online sector is growing as buyers look for more convenient ways of shopping and easier ways to compare products, industry analysts say.

The Beaverton, Oregon-based shoe and clothing giant reported in December an increase in sales of 9 percent in its second quarter and 6 percent growth to reach a revenue of $4.6 billion.
