Query: How many seasons did Leave It to Beaver have?
Leave It to Beaver ran for six full 39-week seasons (234 episodes). The series had its debut on CBS on October 4, 1957. The following season, it moved to ABC, where it stayed until completing its run on June 20, 1963. Throughout the show's run, it was shot with a single camera on black-and-white 35mm film.[2] The show's production companies included the comedian George Gobel's Gomalco Productions (1957–61) and Kayro Productions (1961–63) with filming at Revue Studios/Republic Studios and Universal Studios in Los Angeles. The show was distributed by MCA TV.

The closing sequence for the first season featured a simple, dark background as the credits rolled.[15] In the second season, Wally and Beaver are seen walking home from school with their schoolbooks and entering the house through the front door.[16] In the third through fifth seasons, Wally and Beaver are seen walking towards the Pine Street house.[17] Beaver carries a baseball glove and limps along the curbstone.[17] In the last season, Beaver, arguing with Wally as the two are walking home, pushes Wally into the street and they start chasing each other around a tree and into the house.[18]
The series entered syndication in many cities four days following completion of the ABC summer repeats. By the mid-1970s, the show was only on in a few markets, one of which was Atlanta, Georgia on Ted Turner's Channel 17, WTCG. In 1976, when WTGC went on satellite and became a Superstation available nationwide, Leave It To Beaver was exposed nationwide. From the late 1970s to the mid-1980s, Leave It To Beaver gained in popularity. In Chicago, the show aired on a shaky independent station 44 WSNS. But when WSNS began to phase in subscription TV in 1980, they did not renew and WGN-TV, which also became a Superstation picked it up. So in the early 1980s the show was airing in most large, major, and medium TV markets. It also aired on CBN from 1981 until 1984. Still, TBS and WGN showed it for many years in the late 1980s and into the 90s (TBS sometimes running it back-to-back with the New Leave It to Beaver on occasion), and briefly on Nick at Nite from July 12, 2002 – August 10, 2002 as part of TV Land Sampler.[65] It aired on TV Land in July 1998 where it has been shown until November 2012. Today, NBC Universal Television owns the syndication rights and all properties related to the series.

The fourth season of "Leave It to Beaver" debuted on ABC October 1, 1960 with "Beaver Won't Eat" and aired its last episode, "Substitute Father", June 24, 1961. At forty-thousand dollars, "In the Soup" (May 6, 1961) would be the most expensive episode produced during the series' run. Like the previous three seasons, the fourth season consists of 39 black-and-white, full-screen, half-hour episodes (with ads) shot on 35mm film.
Nick McHatton from "TV Fanatic", gave a 4.8 star rating out of 5, stating: "'Leave It To Beavers' is the episode we've all been waiting for. In many ways it is the perfect episode to transition towards the end of the season. So many of its plot culminations are moments we've been rooting for and wanting and waiting to see since the beginning of the series."
Richard Correll joins the show and remains for the duration as Beaver's classmate and friend, Richard Rickover. Karen Sue Trent joins the cast as Penny Woods. Penny would replace Judy Hensler as Beaver's classroom nemesis in the following season when Jeri Weil leaves the show.
Each season had an individually filmed sequence for the opening credits. In season one, for example, a cartoon-like drawing of a freshly laid concrete sidewalk was displayed with the show title and stars' names scratched into its surface, while in the final season, the Cleavers left the house through the front door carrying picnic items. (See List of Leave It to Beaver episodes for specific season opening sequences.)[15] Billingsley was the first to be introduced in all opening sequences, followed by Beaumont and Dow. Mathers was introduced last, with the voice-over line, "...and Jerry Mathers as The Beaver".[15]
Following the season's third episode, "Beaver Becomes a Hero", Jeri Weil leaves the show with thirty-one appearances as Beaver's classroom nemesis, Judy Hensler under her belt. Karen Sue Trent then fills the classroom nemesis role as snooty Penny Woods.
Although the sitcom was short lived, and cut after its first season, it did have two award nominations. At the 9th Youth in Film Awards on December 5, 1987, hosted by the Youth In Film Association, "Sanchez of Bel Air" was nominated for the Best Cable Series category. Ultimately, it lost to "The New Leave It to Beaver". At the same show Alitzah Wiener was nominated for Best Young Actress in a Cable Series or Special. Having the same fate as "Sanchez of Bel Air", she lost to Kaleena Kiff of "The New Leave It to Beaver".
Critics of the period were generally favorable to "Leave It to Beaver". "TV Guide" dubbed the show "the sleeper of the 1957-58 season". But the season did not break into the Nielsen Top 20. It was in the first season, however, that the show received its only Emmy nominations in its history: the first nomination, for Best New Program Series of the Year, and the second, for Best Teleplay Writing - Half Hour or Less (Joe Connelly and Bob Mosher) for the premiere episode, "Beaver Gets 'Spelled".
"Leave It to Beavers" received positive reviews. The A.V. Club's Kevin McFarland gave the episode a "B" grade and wrote, "About two thirds of the way through 'Leave It To The Beavers,' one of the beaver Wesen tells Nick that 'bravery isn’t in our nature,' but our hero refuses to believe that ancient standard. He's still relatively new to investigating matters of the Wesen world, and wants to believe in change; that any creature, like Bud, the first beaver he encountered, can muster up enough bravery to stand up to anything, from bridge trolls enforcing archaic tradition to Reapers out collecting heads. Though there is a moral built into that conversation, and the episode at large, it's hard to believe that this show would reach for an episodic moral over darkly lit action sequences, which inevitably pop up in the last ten minutes this week. It's a thrilling conclusion to an episode filled with a lot of talking and stunted inaction. Over the back half of this season, I've gone from wanting this show to succeed while feeling frustrated at how it squanders potential, into largely enjoying everything with a few reservations. That trepidation was more pronounced tonight that it has been the past two weeks, but still, I'm very pleased with the progress."
In the off-season, the Athletic Association of Western Universities was renamed the Pacific-8 conference. As good as the Giant Killers were, many expected the 1968 Beavers to be even better. Just four of the 22 starters graduated, perhaps the biggest loss was the kicker, Mike Haggard. Another starter, Jess Lewis, did not return in 1968 because he competed for the United States on the Olympic wrestling team. A top ten team returning the vast majority of their starters did not go unnoticed. Playboy rated Oregon State as the #1 team in their season preview. The pollsters rated the Beavers #6, Oregon State's highest-ever ranking up until that time.
This season aired on The Disney Channel as "Still the Beaver". The season was split into two halves, and could be considered as two separate seasons. Most of the episodes during the second half of the season, which begins with "Escape from the Salt Mines", aired during the summer and fall of 1985, which is technically within the span of the 1985-86 TV season. The episode "Dear Pen Pal II" was produced to be The Disney Channel's series finale and features only clips from Season 1, but did not actually air until the third season on TBS.
Universal Studios Home Entertainment released the first two seasons of Leave It to Beaver on DVD in Region 1 in 2005/2006. Season one was released in two versions: an inexpensive cardboard slip-cased collection and a costlier version in which the DVDs were contained in a retro-styled, plastic photo album tucked inside a plaid metal lunch box displaying portraits of the cast on its exterior. Both of these seasons were released in the troublesome DVD-18 format which plagued many of Universal Studios' boxed set releases.
"Leave It to Beaver" debuted Friday, October 4, 1957 at 7:30 P.M. (EST) on CBS with "Beaver Gets 'Spelled". Mid-season, the show was rescheduled to Wednesday nights at 8:00 P.M. In the second season, the show would move to ABC. The first season completed its run on July 16, 1958 with "Cat Out of the Bag". The first season consists of 39 black-and-white, full-screen, half-hour episodes (without ads) recorded on 35mm film. 
The first season of "Veronica Mars" features a different "case of the week" each episode, and the season-long mystery of Lilly Kane's murder. In addition to developing a separate mystery for each episode, the writers also had to provide clues that would lead to the murder's resolution in the season finale. The murder mystery plot was planned from the beginning of the season and the killer's identity remained the same throughout production. Thomas said that at the beginning of the season, "I know the broad strokes, I know who did it, I know how it was done, I know the big arcs, but we're always filling in the details. Those are week to week. It's a week to week challenge in the writers room figuring out how much information we want to dole out to the audience."
Beginning in "Leave It To Beaver"'s fifth season which launched in September 1961, Fred Rutherford began appearing less often in episodes because Richard Deacon began appearing as a regular on "The Dick Van Dyke Show". He reprised the role in the 1983 reunion television movie, "Still the Beaver", but Deacon died before the spinoff television series "The New Leave It to Beaver" was launched in 1985. By that time, Clarence and Beaver have started their own business.
The second season of the American television situation comedy "Leave It to Beaver" premiered on October 2, 1958 and concluded on June 25, 1959. It consisted of 39 episodes shot in black-and-white, each running approximately 25 minutes in length. This was the first season that the show was originally aired on ABC after the first season was televised on CBS.
The sixth season of "Leave It to Beaver" debuted on ABC September 27, 1962 with "Wally's Dinner Date" and aired its last episode, "Family Scrapbook", June 20, 1963. Like the previous five seasons, the sixth season consists of 39 black-and-white, full-screen, half-hour episodes (with ads) shot on 35mm film.
In the opening sequence, the camera shows the Cleaver's front yard and June walks out of the house with a picnic basket. She then looks back to see Ward leaving the house with more picnic supplies. He looks back to see Wally who runs out looking back at Beaver who runs out of the house at full speed, closing the door behind him. They then get in their car while Beaver looks out the back window smiling. The closing sequence shows Beaver and Wally walking and arguing which leads into a chase that leads them into the house.
Norman Abbott, David Butler, or Hugh Beaumont directed most of the episodes. Episodes were written by either the writing teams of Joe Connelly and Bob Mosher or Dick Conway and Roland MacLane. 
All four cast members appeared in every episode. Rusty Stevens who played Larry Mondello in the first four seasons returns in the finale, Family Scrapbook, in flashbacks.
In this season, Wally and Beaver are both finishing phases of their education. Beaver is in eighth grade at Grant Ave. Grammer School and is preparing for high school. Wally is in twelfth grade and is finishing high school.
In 1983, CBS aired the reunion telemovie "Still the Beaver" starring Jerry Mathers. Other members of the original series cast reprised their roles. In 1985, a sequel to the original series was produced called "Still the Beaver", again starring Jerry Mathers and other original cast members. The series lasted one season on the Disney Channel before being picked up by TBS in 1986 and renamed "The New Leave It to Beaver". The series aired until 1989. In 1997, the feature film "Leave It to Beaver" was released starring young Cameron Finley as the Beaver.
The third season of "Leave It to Beaver" debuted on ABC October 3, 1959, with "Blind Date Committee" and concluded its run June 25, 1960, with "Beaver's Team". The show moved from its Thursday time-slot to Saturday at 8:30 P.M., where it remained until September 1962, when it moved yet again for the final season. Like the first two seasons, the third consists of 39 black-and-white, full-screen, half-hour episodes (with ads) recorded on 35mm film.
A typical episode generally follows a simple formula: Beaver or Wally (or both) get into a predicament they then try to get out of, and then face their parents for a lecture regarding the event. Lectures sometimes take the form of fables,[36][37] with Ward allowing the boys to discover their moral meanings and applying those meanings to their lives. Occasionally, when offenses are serious, punishments such as being grounded[38] are dealt the miscreants. The parents are sometimes shown debating the best approach to the situation. Other episodes (especially in earlier seasons) even reverse the formula, with Ward making a parenting mistake and having to figure out how to make up for it.
