Getting that many in a day is unusual. Net traffic is usually measured in thousands. Traffic dropped slightly Thursday, according to Nielsen numbers released Friday. ABC got more than 1 million users on Wednesday. Media Metrix had CBS at 408,000 and Fox News at 402,000, while Nielsen had Fox at about 674,000 and CBS at 541,000.
Discrepancies are common because traffic measurement techniques are still new.
Traffic grew steadily during the week. Wednesday's CNN audience was five times that of the same period last week. ABC had a nearly fourfold increase. Fox's increase was about 50 percent. The figures track unique visitors, meaning the same person visiting a site over and over would be counted only once.
