Happy Days season 11

The eleventh and final season of Happy Days, an American television sitcom, originally aired on ABC in the United States between September 27, 1983, and July 19, 1984. The show was created by Garry Marshall, under the production company Miller-Milkis-Boyett Productions and Henderson Production Company, Inc., in association with Paramount Television.

Background
Like the three previous seasons, this season also consisted of 22 episodes, all of which were directed by Jerry Paris. When its spin-off Joanie Loves Chachi was canceled in 1982, Scott Baio and Erin Moran returned to Happy Days, after being special guest stars during its tenth season, which also marked the departure of Cathy Silvers, who returned on the two-part series finale in 1984. Meanwhile, another regulars from season ten –Linda Purl, Crystal Bernard, Billy Warlock and Heather O'Rourke– did not return for this season.

This season marked the return of Ron Howard and Don Most in three years, after the seventh season's finale in 1980; while Anson Williams, despite still being credited on the opening credits for this season, he only appeared on five episodes; eventually, Williams and Most did not appear on the finale. Pat Morita, who played Arnold, made his final appearance on the first episode of the season; while Al Molinaro, who played Al, returned for the series finale. The season began filming in May 1983 and ended in November of that year. Also, the title theme song was re-recorded in a more modern style. It featured Bobby Arvon on lead vocals, along with several backup vocalists. To accompany this version, new opening and closing credits were filmed, and the flashing Happy Days logo was redesigned, to make it more sitcom friendly.

After ten consecutive seasons leading ABC Tuesday night at 8:00 PM, the network was forced to regroup after its most-successful spin-off Laverne & Shirley ended its run in May 1983, and most importantly, a new show, The A-Team debuted on NBC in January of that year and began airing on the same night and timeslot as Happy Days, which saw its viewership decline during the 1982-83 television season, as it ended at number 28 on the Nielsen ratings, while The A-Team ended at number ten. For the 1983-84 season, the show left its popular 8:00 PM timeslot and was moved back half an hour to 8:30 PM, and a new series, the ultimately short-lived show Just Our Luck, took its place. It stayed on that timeslot, until the series finale, aired on May 8, 1984. However, there were five "leftover" episodes that ABC didn't have time to air during the regular season due to the Winter Olympics and the spring run of a.k.a. Pablo. Four of these aired on Thursday nights during the summer of 1984; the fifth ("Fonzie's Spots") aired on syndication on September 24, 1984. Due to its timeslot change and the rising popularity of The A-Team, ratings fell even further, ending at number 63, the show's lowest-watched season.
