"Steam is good for retail. If you look at some examples of things we’ve done in the past, it shows that," Valve's Steam boss Jason Holtman tells MCV in an excerpt from their interview with Holtman and Doug Lombardi. "One thing we did with Left 4 Dead was have a free weekend, so every one of our customers were able to play the game. At the end of the weekend we give people the option to buy the game, and the Steam sales went up," he explains. "But something that people didn’t see was that retail sales spiked, too. And of course this happens. Everyone is talking about the game, but not everyone has a credit card, or credit on their card. Not everyone wants to make a purchase right away and lots of people are heading into the High Street anyway. So when we do promotions, we see sales spikes both digitally and online. People who use Amazon still go to bookstores. You can buy almost anything online, but people still go out to the High Street to buy things."
