Like Hollywood stars stuck in a rut, Barry Diller and John C. Malone are always cast in the same contrasting roles. Mr. Diller, 65, lives a razzle-dazzle life of extravagance and celebrity. If he isn't flying off to Capri with his wife, the socialite and fashion designer Diane von Furstenberg, he is running his company, IAC/InterActiveCorp, from a sculptured $133 million tower designed by Frank Gehry on the Hudson River.
Resembling a melting iceberg, the building is near the marina where Mr. Diller berths one of his several yachts -- toys that have doubled as places to hold board meetings.
Mr. Malone, 66, rules over Liberty Media from the high plains of Colorado, where he wears flannel, takes afternoon hikes with his dogs and fastidiously avoids the spotlight. A low-key cable pioneer, Mr. Malone has located his headquarters in a mundane office park unlikely to catch the eye of any architecture aficionado.
Mr. Malone also has his indulgences; these run toward a custom-built motor home and 75,000 acres of wooded Maine real estate.
