Newhart's most notable exposure on television came from two long-running programs that centered on him.
In 1972, soon after Newhart guest-starred on The Smothers Brothers Comedy Hour, he was approached by his agent and his managers, producer Grant Tinker, and actress Mary Tyler Moore (the husband/wife team who founded MTM Enterprises), to work on a pilot series called The Bob Newhart Show, to be written by David Davis and Lorenzo Music.
He was very interested in the starring role of dry psychologist Bob Hartley, with Suzanne Pleshette playing his wry, loving wife, Emily, and Bill Daily as neighbor and friend Howard Borden.

The Bob Newhart Show faced heavy competition from the beginning, launching at the same time as the popular shows M*A*S*H, Maude, Sanford And Son, and The Waltons.
Nevertheless, it was an immediate hit.
The show eventually referenced what made Newhart's name in the first place.
Apart from the first few episodes, it used an opening-credits sequence featuring Newhart answering a telephone in his office.
According to co-star Marcia Wallace, the entire cast got along well, and Newhart became close friends with both Wallace and co-star Suzanne Pleshette.

In addition to Wallace as Bob's wisecracking, man-chasing receptionist Carol Kester, the cast included Peter Bonerz as amiable orthodontist Jerry Robinson; Jack Riley as Elliot Carlin, the most misanthropic of Hartley's patients; character actor and voice artist, John Fiedler as milquetoast Emil Petersen; and Pat Finley as Bob's sister, Ellen Hartley, a love interest for Howard Borden.
Future Newhart regular Tom Poston had a briefly recurring role as Cliff "Peeper" Murdock, veteran stage actor Barnard Hughes appeared as Bob's father for three episodes spread over two seasons, and Martha Scott appeared in several episodes as Bob's mother.

By 1977, the show's ratings were declining and Newhart wanted to end it, but was under contract to do one more season.
The show's writers tried to rework the sitcom by adding a pregnancy, but Newhart objected: "I told the creators I didn't want any children, because I didn't want it to be a show about 'How stupid Daddy is, but we love him so much, let's get him out of the trouble he's gotten himself into'."
Nevertheless, the staff wrote an episode that they hoped would change Newhart's mind.
Newhart read the script and he agreed it was very funny.
He then asked, "Who are you going to get to play Bob?"
Coincidentally, Newhart's wife gave birth to their daughter Jenny late in the year, which caused him to miss several episodes.

In the last episode of the fifth season, not only was Bob's wife, Emily, pregnant, but his receptionist, Carol, was, too.
In the first show of the sixth season, Bob revealed his dream of the pregnancies and that neither Emily nor Carol was really pregnant.

Marcia Wallace spoke of Newhart's amiable nature on set: "He's very low key, and he didn't want to cause trouble.
I had a dog by the name of Maggie that I used to bring to the set.
And whenever there was a line that Bob didn't like—he didn't want to complain too much—so, he'd go over, get down on his hands and knees, and repeat the line to the dog, which invariably yawned; and he'd say, 'See, I told you it's not funny!'"
Wallace has also commented on the show's lack of Emmy recognition: "People think we were nominated for many an Emmy, people presume we won Emmys, all of us, and certainly Bob, and certainly the show.
Nope, never!"

Newhart discontinued the series in 1978 after six seasons and 142 episodes.
Wallace said of its ending, "It was much crying and sobbing.
It was so sad.
We really did get along.
We really had great times together."
Of Newhart's other long-running sitcom, Newhart, Wallace said, "But some of the other great comedic talents who had a brilliant show, when they tried to do it twice, it didn't always work.
And that's what... but like Bob, as far as I'm concerned, Bob is like the Fred Astaire of comics.
He just makes it look so easy, and he's not as in-your-face as some might be.
And so, you just kind of take it for granted, how ext
