According to reports, Yahoo Inc. is going to show off a major upgrade to it advertising network tommorow, called “Amp”,  with an online video demonstration

Yahoo promises Amp will make it easier for advertisers to aim their messages at specific demographic groups across scores of Web sites.

“This is a revolutionary approach that will allow marketers and publishers to deliver a more compelling experience for consumers,” said Hilary Schneider, Yahoo’s executive vice president of global partner solutions.

Amp will rely heavily on data that Yahoo collects about people’s preferences at its own Web site, as well as other online destinations and displays  ads tailored to their individual interests.
