In the month since Apple opened an online software clearinghouse called the App Store, users have downloaded more than 60 million programs for the iPhone, Chief Executive Steve Jobs said in an interview tody.

While most of those applications were free, Apple sold an average of $1 million a day in applications for a total of about $30 million in sales over the month, Jobs said.

If sales stay at the current pace, Apple stands to reap at least $360 million a year in new revenue from the App Store, Mr. Jobs said. “This thing’s going to crest a half a billion, soon,” he added. “Who knows, maybe it will be a $1 billion marketplace at some point in time.”
