‘The Flash’ Gives The CW Its Biggest Premiere in Five Years

Comic-book adaptation lands network’s best premiere best numbers since the 2009 debut of “The Vampire Diaries”

“The Flash” definitely hit the ground running with its premiere Tuesday night.

The CW’s latest comic-book adaptation, which stars Grant Gustin as the red-clad, super-speedy hero, debuted to 4.54 million total viewers, making it the network’s most-watched series premiere in more than five years, since the season kickoff of “The Vampire Diaries” in 2009.

In the 18-49 demographic most important to advertisers, the “Flash” premiere performed particularly well, especially for the younger-skewing network, scoring a 1.8 rating/6 share in the demo — also a network high since the “Vampire Diaries” premiere.

Across the entire history of The CW, “The Flash” stands as the third most-watched and highest-rated series premiere, bested only by the aforementioned “Vampire Diaries” premiere and the series debut of “90210.”

Overall for Tuesday, The CW averaged 3.66 million total viewers.
