They may be calling it “Crisis on Earth X,” but there were no worries for the CW last night as the net hit its best Monday result among the key demo in six years and its most watched Monday in almost nine years.

With an overall rating of 0.9/3 and 2.6 million viewers, the home of Supergirl (0.9/3) and a special Monday Arrow (0.9/3) hit season highs as well on Night 1 of the annual two-night crossover. Those highs also extended to the show’s audience, with 2.65 million for the former and 2.54 million for the latter.

Ahead of tonight’s The Flash and DC’s Legends of Tomorrow with a lot more than wedding bells and love triangles, the Nazi-punching crossover saw the Melissa Benoist-led Supergirl leap 80% among adults 18-49 from last week. The Stephen Amell-starring archer series hit the bull’s-eye with a 200% demo rise from its last regular scheduled airing November 23.

However, both Supergirl and Arrow saw declines from last year’s crossover episodes with an 18% and 31% drop, respectively.

The CW wasn’t the only one with a crossover last night as the ABC affiliate in Houston and the NBC affiliate in Baltimore aired Monday Night Football pitting the Ravens and Texans. The numbers could see a greater than usual adjustment, but right now the Comcast-owned NBC is tops in the demo with a 1.7/6 and the Disney-owned ABC has the biggest audience Monday with 8.63 million viewers.

For ABC, its annual CMA Country Christmas (1.2/4) special was up 20% among the 18-49s over last year and The Good Doctor (1.8/7) was even with last week’s final numbers. A hit for the network so far, the new medical drama easily won its 10 PM time slot with a 50% jump over NBC’s A Very Pentatonix Christmas (1.2/5) special and a flat Scorpion (0.9/3) on CBS. That NBC music special stumbled 14% from its December 14, 2016 airing.

Still, The Voice (1.9/7) was up 12% from its November 20 airing to again finish as the night’s highest rated and, with 9.75 million tuning in, most watched show.

The House of Moonves saw Kevin Can Wait (1.2/5) and Superior Donuts (1.0/4) also even with last week, like Scorpion. Man With a Plan (1.1/4) and 9JKL (0.9/3) were up a tenth.

Fox was all encores last night. And in case you forgot…
