This talk is part of the Triangle Computer Science Distinguished Lecturer Series



The use of the internet has led to the creation of fundamentally new forms of advertising.  In turn, this advertising provides the financial support for many on-line companies and technological breakthroughs.

The development of online advertising has raised many new questions in economics, mathematics, computer science and engineering, particularly around the design of auctions and markets, and in the design of algorithms to efficiently manage them.  In this talk, we will survey a few problems in internet advertising and discuss some algorithmic and game-theoretic issues that arise.  We will discuss problems both in sponsored search and in display advertising.  We will describe  the applications, the algorithmic problems that arise, and the solutions obtained. In particular, we will discuss the problem of how an advertiser should allocate its budget among various keywords in a sponsored search auction, and how a publisher should decide which display ads to accept.
