Internet Retailer reports that Nielsen/NetRatings found an 11 percent rise in online shopping on this year's Black Friday, the day after Thanksgiving. Of that holiday frenzy, eBay saw the most activity, with traffic twice that of nearest rival Amazon.com. Wal-Mart was a distant third with a bit more than half of Amazon.com's visits. Toys and games saw the biggest year-over-year jump, gaining 152 percent. Electronics sites just about doubled in traffic.
