About 1959-1961 there was a transition from the popular 17 and 21 inch rectangular CRTs to 19 and 23 inch CRTs, with the major difference being slightly more square corners. Most of this newer generation of CRTs also incorporated built in implosion protection and no longer required a separate safety glass. This generation, in general had higher deflection angles and smaller neck sizes than the rectangular CRTs of the 50s. While a few round tube sets were produced in the early 50s (i have a 16 inch 1951 Philco with a round CRT, and of course there was that 30 inch round DuMont!), most 50s B/W TVs were rectangular.
