Says CTO Tim Conrad:
I’ve been looking at it for seven years. I was ready to give it a fresh coat of paint. We started on it about a year ago. But even earlier than that, we’d been talking about it. There were core navigation problems that needed fixing. At first, we had been talking about more incremental changes, with the site still operating in Flash. But then last summer, it became clear that browsers with full HTML5 capabilities had gained enough support. We realized we could do the full Pandora experience without Flash.
Pandora recently went public, raising over $100 million and now has a market value of $3 billion.
The company says it now has 3.6 percent of the U.S. radio listening market share, a 50 percent increase from last year.
