We're still waiting on total viewer information as well as 18-49 demographic viewers, but the season two premiere of Jericho performed very poorly. While we don't have enough data to be absolutely definitive, we have enough where the TVbytheNumbers.com magic 8 ball is saying "all signs point to cancel".
It performed dead last in the 10pm slot in terms of HH ratings in the overnights with a 4.1. A new Boston Legal had a 5.2 and a rerun of Law & Order: SVU had a 6.3 and won the time slot. I'm sure there will be huge talk about DVR numbers, the numbers being off because downloads leaked early, etc, but that's just talk. Jericho has a loyal following, but that loyal following is NOT 10 million strong sadly, or even close.
By way of comparison Jericho made its season one debut on 9/20/2006 with a 7.6 HH rating. The season one finale on 5/9/07 had a 5.2. So a 4.1 really bites (the L&O: SVU rerun outperormed it by more than 50%!)
Sorry to be the bringer of bad news, but that news looks bad. Viewer and 18-49 data are now up: things looked a little better with the viewer and demo info, but still not great.
