CBS has given full season orders to all four of its new dramas: "NCIS: New Orleans," "Scorpion," "Madam Secretary" and "Stalker."

The pickups include three of the four most-watched new shows launched on television this season, and three series that rank among the top 15 of all primetime programs. The odd man out there is "Stalker."

Thanks in part to the freshman dramas — and in perhaps larger part to "Thursday Night Football" — CBS has won the first four weeks of the fall season for the sixth consecutive year, up five percent year-over-year.

"These four shows have had an immediate impact on our schedule by improving nights, winning time periods and adding more hours of success across our primetime line up," said Nina Tassler, chairman, CBS Entertainment.

"NCIS: New Orleans" is the season's most-watched new series, averaging 18.16 million total viewers, as well as a 2.8 rating in the advertiser-sought 18-49 demographic, according to Nielsen's most current ratings through Oct. 19.

"Scorpion" is the No. 2 new series to the aforementioned latest "NCIS" installment, averaging 15.17 million viewers and an even-higher 3.6 rating in the key demo.

"Madam Secretary" ranks as the fourth-best new series with 13.53 million viewers. It is, however, much less of a hit in the demo, averaging a mere 1.8 rating.

"Stalker" is perhaps the surprise order of the bunch. It is averaging 9.49 million viewers and a 2.1 in the key demo.
