Papa John's has just passed the one billion dollar mark in Internet pizza sales.
Online orders are hotter than a pepperoni pie covered with red pepper.
The company says Internet orders have climbed more than 50 percent a year since the service started seven years ago.
The hottest markets for Papa John's Internet orders include the Austin, Texas, and Washington, D.C., areas.
Officials of Papa John's promise new wrinkles to high-tech ordering, but they're not revealing just what's in the oven.
