March 15, 1977

Three's Company first aired.  It is based on the British sitcom Man About the House.

The story revolves around three single roommates: Janet Wood (Joyce DeWitt), Chrissy Snow (Suzanne Somers), and Jack Tripper (John Ritter), who all platonically live together in a Santa Monica, California apartment building owned by Stanley Roper (Norman Fell) and Helen Roper (Audra Lindley). Following Somers' departure in late 1981, Jenilee Harrison joined the cast as Cindy Snow, who was soon replaced by Priscilla Barnes as Terri Alden. 

After Norman Fell and Audra Lindley left the series for their own sitcom, Don Knotts joined the cast as the roommates' new landlord Ralph Furley.

The show, a comedy of errors, chronicles the escapades and hijinks of the trio's constant misunderstandings, social lives, and financial struggles, such as keeping the rent current, living arrangements and breakout characters. A top ten hit from 1977 to 1983, the series has remained popular in syndication and through DVD releases.

After crashing a party and finding himself passed out in the bathtub, cooking school student Jack Tripper meets Janet Wood, a florist, and Chrissy Snow, a secretary, in need of a new roommate to replace their departing roommate Eleanor. Having only been able to afford to live at the YMCA, Jack quickly accepts the offer to move in with the duo.

However, due to overbearing landlord Stanley Roper's intolerance for co-ed living situations, even in a multi-bedroom apartment, Jack is allowed to move in only after Janet tells Mr. Roper that Jack is gay. Although Mrs. Roper figures out Jack's true sexuality in the second episode, she does not tell her husband, who tolerates but mocks him. Frequently siding with the three roommates instead of her husband, Mrs. Roper's bond with the roommates grows until the eventual spinoff The Ropers.

Jack continues the charade when new landlord Ralph Furley takes over the apartment complex because Mr. Furley insists that his hard-nosed brother Bart (the building's new owner) would also never tolerate such living situations.

The Last Show (The Mary Tyler Moore Show) The 168th episode and series finale of the television sitcom, The Mary Tyler Moore Show, and was written by Allan Burns, James L. Brooks, Ed Weinberger, Stan Daniels, David Lloyd and Bob Ellison. 

It was first broadcast on CBS on March 19, 1977. The episode won an Emmy Award for "Outstanding Writing in a Comedy Series." In executive producer Allan Burns' "Outstanding Comedy Series" acceptance speech at the 29th annual prime time Emmy Awards, he stated, "We kept putting off writing that last show; we frankly didn't want to do it. I think it said what we wanted it to say. It was poignant, and I believe The Mary Tyler Moore Show was, in the long run, important for many women."

Plot summary

The new owner of WJM-TV is firing people left and right, and wants to do something about the Six O'Clock News' low ratings. Surprisingly, Lou, Mary, Murray, and Sue Ann are fired, but the person widely perceived as the cause of the Six O'Clock News' low ratings, Ted, is retained.

Mary takes the news particularly hard. To cheer her up, Lou arranges for old friends Rhoda and Phyllis to fly to Minneapolis for a surprise visit at Mary's apartment.

After their final news broadcast together, in which Ted gives a sincere but comical sendoff to his colleagues on the air, the Six O'Clock News' staff, along with Georgette, gather in the newsroom to say goodbye to each other. The memorable and oft parodied scene culminates in an emotional huddle, during which nobody wants to let go, and, needing some tissues, the group shuffles en masse toward a box on Mary's desk. After final goodbyes, everyone exits the newsroom singing "It's a Long Way to Tipperary." Finally, a very emotional Mary looks back, then bucks up and smiles before turning off the lights and closing the door.
