John Ritter does a promo for the syndicated reruns of his sitcom, only on Ch. 61!

Three's Company was unmistakably a hit in syndication I was fortunate at the time to be able to catch reruns on KTTV Los Angeles and KMPH Fresno so got to see TC twice a day which not many sitcoms had that option. And it was always during that time period just after the cartoons but before the evening game shows.
