	But not because of the TCR-100.  They sold a crap-load of them.  And 
stations made a lot of money using them.
	I sorta disagree with you about their needing a standalone TBC.  This 
was still a quad machine and quad's timebase errors were quite 
different from the errors corrected by standalone TBCs of the time.  
Nearly every one of those standalone TBCs were made for helical VTRs 
which had slower-changing and larger-deviation timing errors.  It made 
sense for RCA to use what they had in use on TR-60's and TR-70's of the 
era.  Those systems actually worked quite well.
	TCR-100 did have one marketing advantage over ACR-25 which made it 
desirable in many smaller markets:  The machine could share its signal 
system and error correction system with a co-located TR-60.  This saved 
the stations a lot of money.  Though I never worked with one of these 
versions of the machine, I could see how this feature would make TCR 
popular with station owners (and probably ONLY with station owners).
