Also from Mediapost, an online advertising idea that finally makes sense. This article describes a tactic now used by the New York Time Online that delivers that same marketing messages to visitor based on sessions. It know allows an advertiser to advertise based on daypart rather then pure impression.
In the latest issue of MediaPost, an article states that a DoubleClick study reports that catalogers and retailers have the highest response rates. Not surprising since they have been trusted sources with strong brands built over time. Not like the spammers who "claim" that you have opted into their networks and fill your Inbox with crap!
Give it a break, spammers. No one wants the shit you have to sell!
