I will have up to 10 shows depending on how strong the individual letters are. Since shows starting with The are numerous, any show that starts there and with just A, its letter will be counted as the second word.

A
1. The Andy Griffith Show- Black and white era is one of the best shows ever made. Color era is not nearly as good but still better than a lot of shows.
2. Adam-12- one of the best police dramas ever made
3. The Alfred Hitchcock Hour/Alfred Hitchcock Presents
4. The American Bible Challenge- too bad GSN or other stations don't rerun this anymore
5. All Creatures Great and Small (2020)- I am sure the 1978 version is great as well, but just including what I have seen.
6. Around the World in 80 Days (2021)
7. The Addams Family (1964)
8. Almost Paradise
9. Awake
10. America Says

B
1. Benson
2. Barney Miller
3. Blue Bloods- easily the best crime drama from the 21st century
4. The Beverly Hillbillies
5. Boy Meets World seasons 1-5
6. Bewitched (Dick York era only)
7. Bachelor Father
8. Believe
9. BrainDead
10. Beyond Belief: Fact or Fiction?

C
1. Columbo- Peter Falk was amazing single handedly carrying the show.
2. Corner Gas- This is easily the best 21st century sitcom ever made, only other to come near it is The Middle.
3. Coach
4. Castle- seasons 1-6 only
5. Cheers
6. The Chase (GSN)
7. Charlie's Angels (1976)
8. The Courtship of Eddie's Father
9. Classic Concentration (Alex Trebek)
10. Cash Cab (Ben Bailey- only the original Discovery run)

D
1. Dragnet '67- So many crime dramas could learn from this with no bad language.
2. Designated Survivor- ABC seasons only
3. The Dick Van Dyke Show
4. Diagnosis Murder
5. Diff'rent Strokes- episodes before Sam and Maggie joined
6. DAG- best one season sitcom ever made
7. Dispatches from Elsewhere
8. The District
9. (A) Different World
10. Double Dare (Alex Trebek)

E
1. Early Edition- best TV show of all time
2. Eight is Enough
3. Everybody Loves Raymond
4. 8 Simple Rules for Dating my Teenage Daughter- what a shame John Ritter died so prematurely
5. Emergence
6. Emergency!
7. Extreme Cheapskates- a rare show worth watching on TLC, only thing they had better was Outrageous 911.
8. 800 Words
9. The Ed Sullivan Show- If only full episodes of this were available, all I have seen was a few best of airings on Decades.
10. Extant season 1

F
1. Fame- 2nd best TV show of all time, only show I have considered unseating Early Edition as the overall #1 in my top 100 lists.
2. Frasier (1993)- First six seasons are top notch. Second half of the show tumbled some, but still several good episodes.
3. Family Affair (1966)
4. Fawlty Towers
5. Family Ties
6. 500 Questions- fantastic game show that deserved a lot better ratings
7. The Facts of Life- Charlotte Rae seasons
8. For the People (2018)
9. Family Feud- Richard Karn and John O'Hurley versions only
10. Family Matters

G
1. Grand Slam- GSN's tournament of game show champions. Too bad this has never re-aired since its original run in 2007. :(
2. Granite Flats
3. Gilmore Girls (2000)
4. Greed
5. Gomer Pyle, U.S.M.C.

8. Highway to Heaven (1984)

10. Hawaii Five-O (1968)

I
1. I Love Lucy/The Lucy-Desi Comedy Hour- Since the comedy hour is just another season of I Love Lucy, they will be joined together here in the Is.
2. I Dream of Jeannie
3. It's a Living- This became really good when Crystal Bernard joined the cast in the syndicated run, became even better when Sheryl Lee Ralph replaced Ann Jillian.
4. I'm with Her
5. Indebted- nowhere near as good as The Nanny and Wings, but as said below I doesn't have much options.
6. Nothing- I is a really weak letter. I would probably like I'll Fly Away and I Spy but haven't seen them, Ink with Ted Danson and Mary Steenburgen could be good as well.

J
1. The Jack Benny Program
2. Justice (2006)- Great cast and writing, this deserved a longer run. :(
3. Jeopardy!- No one will top Alex Trebek as host of course. But honorable mentions go to Ken Jennings, Mayim Bialik, and Buzzy Cohen.
4. Joan of Arcadia
5. The Jeffersons
6. The Jeff Foxworthy Show- Season 1 was better than season 2.
7. The Jay Leno Show
8. Jericho (2006)
9. Judge Judy
10. Jay Leno's Garage

K
1. The Kids Are Alright- 2nd best one season sitcom after DAG
2. Kevin (Probably) Saves the World
3. Keeping Up Appearances
4. Kraft Suspense Theatre
5. Nothing- this is a very weak letter. I would probably like Kojak and Kirk but have not seen them.

L
1. Leverage (TNT)
2. Law and Order- Jerry Orbach seasons are the best.
3. The Love Boat (1977)
4. Lincoln Heights
5. The Lone Gunmen
6. Leave it to Beaver
7. Law and Order: Criminal Intent- Vincent D'Onofrio episodes
8. Law and Order: Trial by Jury
9. Lou Grant- I really liked the three episodes I saw awhile back, would be nice to see the whole thing.
10. Lincoln Rhyme: Hunt for the Bone Collector

M- an immensely strong letter, I will double the usual 10 here.
1. Mad About You (1992)
2. M*A*S*H
3. The Middle- by far the best 21st century US sitcom

7. Major Crimes
8. Mr. Belvedere
9. Monk
10. Matlock

10. Numb3rs

5. Outrageous 911
6. Ozzie and Harriet
7. The Odd Couple (1970)
8. Outmatched
9. 1 vs. 100 (Bob Saget)
10. Nothing- O is as weak as M and A are strong. Under its full "The Adventures of" title, Ozzie and Harriet did not make the cut in the As. Owen Marshall, Counselor at Law and the Ron Glass version of The Odd Couple sound interesting, but I have not seen them.

P
1. Petticoat Junction
2. The Practice (1997)- Dylan McDermott seasons
3. Psych
4. Punky Brewster (1984)
5. People Puzzler
6. The Patty Duke Show
7. Password Plus (Allen Ludden)- Alphabetics made this a much improved version of the original.
8. Privileged- Joanna Garcia's best show including Reba. what a shame it flopped :(
9. Promised Land (1996)
10. The Partridge Family- live action only

Q- Naturally nothing with as scarce as this letter is. I would probably like og Quantum Leap being an Early Edition fan but have never seen it.

2. Resurrection
3. Reba
4. The Rockford Files
5. Rebel
6. Ruby and the Rockits
7. Rich Man, Poor Man- Book I
8. Raising Hope
9. Reef Break
10. Runaway (2006)- It would be nice to see all the unaired episodes of this, I might like it even more now being a Donnie Wahlberg fan from Blue Bloods.

S
1. Star Trek: Deep Space Nine seasons 1-6 (Ezri Dax was a terrible replacement for Jadzia Dax).
2. Some Mothers Do 'Ave 'Em- amazing Michael Crawford Britcom most Americans sadly wouldn't have heard of
3. Star Trek: the Next Generation
4. 7th Heaven- I will always be a fan of this show despite the Stephen Collins controversy. Unlike so many, I can separate the actors from the characters they play.
5. Scorpion
6. Switched at Birth
7. Supermarket Sweep (David Ruprecht version only)
8. Seinfeld
9. Sabrina, the Teenage Witch- ABC era definitely better than the WB era
10. Split Second- I like this a lot better than Monty Hall's more famous show Let's Make a Deal.

T- I am including Dick Clark's $25,000 Pyramid with his $100,000 Pyramid in the Os. They are practically the same show, only difference is a few tournament weeks.

X
1. The X-Files seasons 1-7
2. nothing else

Y
