The Nielsen ratings are about to undergo drastic changes, reports John Ourand of Sports Business Journal. "Nielsen has told U.S. TV networks that starting Oct. 3, it will include out-of-home (OOH) viewing in its overnight numbers," he reports. "It also told the networks that it will release numbers from 44 markets at around 1:00pm ET each day. Currently, Nielsen provides numbers from 56 markets at around 8:30am ET each morning."
