NBC's sampling strategy pays dividends

NEW YORK (AP) -- Getting a jump on the fall television season has paid off for NBC.

The fourth-place network debuted some of its new series earlier than its rivals in hopes that viewers would at least try them out. In the case of both the J.J. Abrams thriller "Revolution" and Matthew Perry's comedy, "Go On," that strategy seems to have worked. Both were among Nielsen's top 15 shows last week.

"The Voice" also did well upon its return, topping Fox's singing competition "The X-Factor."
