Clearspring is announcing today at ad:tech in New York a new service called “Clearspring for Advertisers” that will deliver advertisements in the form of interactive widgets.

The announcement does not bring anything particular new to the web, since companies such as Sony Pictures Entertainment, The CW Television Network, Comedy Central, DreamWorks Animation, and Warner Brothers have already distributed ad widgets through the service. We’ve embedded a widget below that was used to advertise the movie Superbad.

The arguments in favor of widgets over regular banner ads depend on the increased engagement levels they provide and their viral nature (fans of a product can embed the widgets in their blogs and social network pages).

More information about the service can be found here on Clearspring’s website.
