The sponsorship idents are bookends to a series of vignettes giving insights into the international gathering, which takes place on January 25-29, showing BT as a global networked IT company.
The 2006 summit is being attended by the likes of new German chancellor Angela Merkel, who is giving the opening address, chancellor Gordon Brown and Michael Chertoff the US secretary for Homeland Security.
Francois Barrault, BT International president, said: "Working with CNN will give us access to senior decision-makers worldwide. We are pleased to sponsor the vignettes, which will spark debate and inform on key issues the forum will cover."
Each vignette will be between 20-50 seconds long, featuring short interviews with leading figures of the business world. The preview vignette to the meeting includes Stelios Haji-Ioannou, the EasyGroup founder, and Jean-Claude Decaux, the president of JCDecaux, looking ahead to the forum.
Jonathan Davies, senior vice-president of CNN International ad sales, said: "BT was looking to reach the C-suite audience and we are the number one platform for that audience."
BT's previous campaign on CNN ran last year. The new campaign broke last week and will continue throughout the Davos coverage, reaching more than 136m households and hotel rooms, on the Europe, Middle East and Africa feed. CNN International Ad Sales struck the deal with Starcom, BT's media agency, with creative idents by Petrol.
CNN has also been named the leading news brand for the world's most senior corporate and financial decisions makers by the Global Capital Markets Survey, conducted by Objective Research.
