The first IMS report was for the week ending March 5, 2010. The bulb infomercial was ranked 20th. This most recent one for the week ended June 11, 2010. Maybe we will see the next one in 3 months or so, maybe sooner if it gets a #1 ranking... lol
I'm pretty sure they have to pay a fair amount of $$ to get monitored and ranked by IMS so that may limit the frequency of the reports.
