Regis Philbin-hosted game show has averaged nearly 9.5 million viewers

Already an early summer success, "Million Dollar Password" has received a vote of confidence from CBS.

The network announced on Tuesday (June 24) that it's ordering six additional episodes of the Regis Philbin-hosted update on the game show classic.

In its first four broadcasts, three on Sundays and a Thursday special, the FremantleMedia North America production has averaged 9.46 million viewers and a 2.6 rating among adults 25-54, winning its each of its time periods in both viewers and that key demographic.

The original "Password" was hosted by Allen Ludden and aired on CBS in both daytime and primetime from 1961 to 1967. "Password" evolved into "Password Plus" and "Super Password" and aired from 1971-1989.

Celebrities on the new CBS "Password" have included Neil Patrick Harris and Rachael Ray.
