The same was true about black and white crt's, all were round for quite
some time. IIRC the first 21" round color crt was a 21AXP22? Ira.

When Color TV's first came on the market in the early 50's all of them
had round CRT's. The first ones were 15" CRT's. Around 1954 RCA
introduced a 21" round CRT and they were the standard until around
1963 when the first rectangular CRTS entered the market. I suspect
this film was made during the short time when both versions were
available. The first practical, consumer color tv was introduced by
RCA in 1953 and they sold about 4,000 of them at a cost of $1,000,
about $8,000 dollars in 2021 dollars...

I believe the round tubes were for the cheaper TVs.

Enjoyed watching that, thanks for sharing.
Any idea what the large round tubes were used for back then?
