The selection of Miller, a former executive at USA Interactive, reflects the company's desire to generate more money by further developing AOL's e-commerce capabilities. At USA Interactive, Miller, 45, oversaw Expedia, Hotels.com and other e-commerce operations.
"Jon's success in building consumer-driven businesses online and offline has given him the right blend of expertise and experience to revitalize America Online," AOL Time Warner CEO Richard Parsons said in a statement Tuesday.
The announcement follows months of questions AOL's business model and accounting practices. Last month, the company confirmed the Securities and Exchange Commission and the Justice Department are looking into its financial statements, particularly in the America Online division.
Miller succeeds Robert Pittman, the company's former chief operating officer who had been heading the division on a temporary basis before he resigned last month.
Pittman was replaced by two executives from the Time Warner side of the business: Don Logan and Jeff Bewkes. Logan, head of magazine giant Time Inc., was tapped to lead a "media and communications" division that includes AOL, Time Inc. and Time Warner Cable. Bewkes, the chairman of HBO, will oversee the "entertainment and networks" group, which includes Warner Bros. movie studio, Warner Music, HBO, The WB and the Turner Networks cable channels such as CNN.
Shares of AOL fell 18 cents to $9.77 in afternoon trading on the New York Stock Exchange.
