One of the sites I frequently read is Economist.com.
The site features free content, as well as premium content that can
only be accessed if you are a subscriber, either online, to the print
edition, or both.
Today however, when I visited the site, I was presented with the
option to get a day pass! You can choose to go to Economist.com and
have only the free content available, or you can choose to view an
advertisement that “unlocks” the premium content for a day. The ad, a
flash presentation that is about 30 seconds long, then provides a link
to the site and premium content is magically available!
I am sure it is all done using cookies or something, so someone,
somewhere will probably find a way to circumvent watching the ad. I
think it’s a great idea though. I’ll gladly sit through an ad to get
access to the entire site!
