The decision to cut and run comes one week ahead of the March deadline set by Arbitron chairman/ceo Steven Morris to decide on Apollo's future.
Barely two years old, Project Apollo made it off the launch pad in January 2006 after more than a year of infighting, politicking, brink-teetering and corporate footdragging.
Even before launch, the two media metrics specialists were forced to scale back the original plans, from a 50,000-household national program to a pilot covering just 6,000 homes.
P&G also planted seed money into the project in 2005, reportedly to the tune of $20m – although a P&G spokesman, while declining to get specific, dismissed that figure as "way high" .
"We respect the decision," said the spokesman, "but we're disappointed Project Apollo will be discontinued, and we remain committed to finding new methods to help us make effective and efficient consumer-centered media decisions."
Meantime, bruised Nielsen Company evp Susan Whiting was in smilin' thru mode: "We have learned a great deal from Project Apollo," she said.
