Fast National ratings for Friday, January 9, 2015.

"Shark Tank" and a strong "Last Man Standing" episode led ABC to a Friday win in the key demographic, while "Blue Bloods" helped CBS to its normal Friday domination overall.

The night's other notable was the final season premiere of FOX's "Glee," which was rather ridiculously low, though comparisons to the musical dramedy's Thursday numbers from last year are probably pointless.

On to the numbers...

Among adults 18-49, ABC averaged a 1.6 rating for Friday night, edging out the 1.5 rating for CBS in the key demographic. NBC and FOX both averaged a 0.7 key demo rating, followed by the 0.2 key demo rating for The CW.
