Things need to go back to those days. Look at what is on TV now. It's sickening.

As for "pregnant" real-life pg actresses could not be seen, had to hide behind objects, such as chairs, tables, people, etc. and wore "loose" clothing to hid the pregnancy.
Censorship was not only the sexual issue but in other issues.
The various social restrictions reflected in the tv censorship is related to the Hayes Code of 1933. One prime example was that pre-code movies, criminals got away with their crimes. Post-code required the criminals to be punished. Also the pre-code "modern" female characters were also made to be the post-code "barefoot and pg" images.
Anyway, the Hayes Code spilt over onto television then, which basically what this is about.
This also brings me back to how progressive Dale Evans character was on The Roy Rogers Show. She was pretty liberated compared to Beaver's Mom, Harriet Nelson, Donna Reed and so on.
We also can talk about the ethnic issue - Ames and Andy, The Goldbergs and so on.
NOTE: I will say Harriet Nelson started to exhibit a more "freer" woman in the 60s. In one episode she drove David's motorcycle - oh, my

I believe one reason Ozzie & Harriet were "allowed" to have a double bed was that viewers knew that they were married IRL. (Of course, so were Lucy and Ricky, and they had twin beds)

Your reply has nothing to do with my post, which is the post you decided to reply to.
EDIT: Sorry if the above is being rude. Speaking which, I wonder why Belly Buttons weren't allowed but outfits showing legs were OK? (as seen in this screenshot from an early 1960s "Ed Sullivan" episode):

Those restrictions were always very confusing, why some things were allowed while others weren't.

Barbara Eden couldn't even show her belly button during the airing of "
I Dream Of Jeannie
". Her belly button! They may as well covered her body in an entire bed sheet.

No, "Mary Kay and Johnny" was the first to show a couple sharing a bed, back in the late-1940s.
I took a quick look through "Ozzie and Harriet" episodes, and it seems that in the very early episodes it was double beds, but they had changed to a single bed by the mid-1950s, as seen in the 9 January 1957 episode "Hairstyle for Harriet", such as in this screenshot with the two in the same bed from that episode:

I don't recall a bedroom scene with Ozzie and Harriet, but it wouldn't have made an impression on me anyway. I read somewhere (can't remember where)that the first "couple" to share a bed were The Munsters.
There was an episode of December Bride, in which Matt and Ruth Henshaw were in their (twin) beds, having a discussion. Ruth gets out of hers and goes to sit, repeat SIT, at the foot of Matt's bed. There was a hue and a cry from the precursors of the Moral Majority.
But throughout it all, my motto was "Dignity! Always dignity!".

Gee. Laurel and Hardy always slept in a double bed.

Steve and Teddy Carella from The 87th Precinct had a double bed although they were never seen lying together in it.

There were a few shows in the 50s/60s where the couple shared the same bed. "Mary Kay and Johnny", "Ozzie and Harriet", "The Goldbergs" (well, at least in a DuMont-era episode I've seen), later in the 1960s "Bewitched", even "The Flintstones".
I read that an episode of "The Johns Hopkins Science Review" back in the 1950s showed a film of a birth, which really surprises me.
British TV (in the 1950s) by comparison was odd, some things were more restricted and some things less restricted. Then by the mid-1960s things got crazythere's stuff in 1960s-era episodes of "Steptoe and Son" which I can't imagine being done on US series of the era.
Since Australian, Swedish, Japanese, etc TV of the 1950s is not available we cannot be assessments of it.
