NBC to CBS on Thursdays at 8 pm by its sponsor RK Reyolds Tobacco to get more access to markets. In April 1957, the show moved back to NBC on Tuesday nights at 9:30 pm. Dwayne Hickman became a break-out star on the show. The series had various recurring models who were given opportunities to act, including Suzanne Alexander, Sally Todd, Norma Brooks, and Joi Lansing. Rod Amateau, who worked on the show, said the reason it was successful was: He [Cummings' character] was unsuccessful. He would never score with these girls because his nephew, his sister, or Schultzy would show up. He had dreams and illusions of being a playboy, but he wasn't making it. His frustration is what made the show funny.|In December 1958, Davis signed to make two more years of the show. The same month, Hickman left for his own show The Many Loves of Dobie Gillis. He was replaced on the show by a six-year-old waif played by Tammy Marihugh. In January 1959, the show celebrated its fifth year. Henning put part of the reason for its success down to the fact that it was a tight operation – Henning wrote most episodes, Cummings directed, and Cummings' wife handled business. During the making of the show, Cummings became increasingly under the grip of his addiction to methamphetamine, although this was kept from the public. End of series The series ended in 1959. Cummings said it was his decision, claiming he needed a break. He also said he had financial considerations, as he wanted to sell the show into syndication and wanted to do that before the show became too dated. He also claimed if he kept making it, he would be hit with a tax bill. Syndication Reruns under the title Love That Bob appeared on ABC's daytime lineup from October 12, 1959, to December 1, 1961.
