The highly-promoted debut of author and comedian Al Franken’s talk show, “The O’Franken Factor,” on the new “Air America” radio network apparently set a record. Air America’s VP/Marketing Leon Colaco says the network’s website handled nearly 500,000 unique visitors in the 22-hour period between 7PM Wednesday and 5PM Thursday. (final numbers from Air America streaming provider RealNetworks will not be available until next week.) This might be the largest number of simultaneous listeners that Real had handled since ABC News’s coverage of the 9/11 attacks on September 12, 2001, which hit 86,700 concurrent listeners.
