My first exposed to atheism on TV was Star Trek S2 E2 "Who Mourns For Adonais?" In this episode, it is made clear Scotty doesn't believe in God(s) I was shocked that a TV network would allow a protagonist character to be an atheist in the late 60s. Since then I have seen more exposure on the subject of Atheism. The most obvious ones include Family Guy, Bones, Young Sheldon, The Big Bang Theory, House, The Mentalist, Doc Martin (BBC), Community, Daria, and The Office. I'm sure I forget a few, but those are the ones I remember.

Bones: The two lead characters were an open atheist and a Catholic. I liked the show, but I hated that the Catholic was more often portrayed as warm and compassionate while the atheist was more often emotionless and socially awkward.

The Orville: Seth McFarland's sci-fi Star Trek homage. The last episode of the first (and only, so far) season is a brilliant treatment of how religions begin in ignorance, develop by power, and fade into obscurity. The ship finds a time anomaly in which each time they visit a particular planet, 700 years have past on that planet. The first trip they accidentally engage a human, and the next time, they realize a religion has formed around them. In subsequent trips, the civilizations and the religion continue to grow..... until the end, which I won't spoil.

Under the Dome: A very strange phenomenon has affected a small town, and any character who tries to explain it with religion is portrayed as a bad character. The episode I watched last night was a pretty good show down between a religious nut and a scientist.

House and I loved his sarcasm..

Firefly

Star Trek. Spock was anything but religious.

Big Bang Theory and Scorpion. I don't even know if Scorpion is on anymore. TV often portrays highly intelligent people as atheist or agnostic. Hmmmmm, wonder if they figured something out.

Dr Who (modern)

Shameless... There's not alot but almost every episode has a small hidden atheist message that is hilarious when you catch them. And that show is the shiznit!

Scoby Dooby Do! They always proved ibwas some crazy guy and that monsters and ghosts were just made up

Big Bang Theory? I don't watch much tv lol.

I think the Simpsons is subtle with their crack at religion. It was great to see my sons watch the show almost religously (sic). They are now adult atheists. How rediculous is Ned Flanders?

My favorite is Dexter No holds barred - it puts religion in it’s place on a regular basis... Must be why I own the entire 8 seasons on DVD!

Don't watch tv.

How can I not mention: FireFly

House!

I don't watch any mainstream TV per se, but the Netflix series "Godless" has been pretty good so far. Frank Griffin's monologue in the third episode (I think) that gives the series its name is awesome.

I know this show isn’t really what your asking about. But I’ve been obsessed with the show Magicians of late. It’s features so much realism in feelings and strength of belief and fighting the common idea.

Shameless... There's not alot but almost every show has a small h
