The name "Boopadoop" derives from the scat singing lyric that was popularized by Helen Kane's 1928 song "I Wanna Be Loved by You".

After a month-and-a-half-long hunger strike by Dagwood to get his parents' blessing, as they strongly disapproved of his marrying beneath his class, they disinherited him.

While the distinctive look and running gags of Blondie have been carefully preserved through the decades, a number of details have been altered to keep up with changing times.

The Bumstead kitchen, which remained essentially unchanged from the 1930s through the 1960s, has slowly acquired a more modern look (no more legs on the gas range and no more refrigerators shown with the compressor assembly on the top).

Although some bedroom and bathroom scenes still show him in polka-dot boxer shorts, Dagwood no longer wears garters to hold up his socks.

Blondie now often wears slacks, and she is no longer depicted as a housewife, since she teamed with Tootsie Woodley to launch a catering business in 1991.

The staff no longer punches in at a mechanical "time clock", nor do they wear green eyeshades and plastic "sleeve protectors".

During the late 1990s and 2000–2001, Alexander worked part-time after high school at the order counter of a fast-food restaurant, the Burger Barn.

In French-speaking countries, the strip is known as Blondinette, while Dagwood is known as Dagobert, a name which is still used in France and Belgium to refer to a kind of sandwich.

Larry Simms played the Bumsteads' son in all the films; his character was originally called Baby Dumpling, and later became Alexander.

Danny Mummert, who had originally been chosen to play Baby Dumpling, took the continuing role of wiseguy neighbor Alvin Fuddle.

Rounding out the regular supporting cast, character actor Jonathan Hale played Dagwood's irascible boss, J.C. Dithers.

In the last film, Beware of Blondie, the Dithers character returned, played by Edward Earle and shown from the back.

In 1943, Columbia felt the series was slipping, and ended the string with It's a Great Life and Footlight Glamour, deliberately omitting Blondie from the titles to attract unwary moviegoers.

Initially a 1939 summer replacement program for The Eddie Cantor Show (sponsored by Camel Cigarettes), Blondie was heard on CBS until June 1944, when it moved briefly to NBC.

Blondie and Dagwood were featured prominently in the cartoon movie Popeye Meets the Man Who Hated Laughter, which debuted on October 7, 1972.

[23] Blondie and Dagwood made a brief animated appearance in The Fantastic Funnies, a TV special focusing on newspaper comics that aired on CBS in 1980.

In a 1989 episode of the animated series Muppet Babies, entitled Comic Caper, Blondie and Dagwood make a cameo appearance.

Over the years, Blondie characters have been merchandised as dolls, coloring books, toys, salt and pepper shakers, paint sets, paper doll cutouts, coffee mugs, cookie jars, neckties, lunchboxes, puzzles, games, Halloween costumes, Christmas ornaments, music boxes, refrigerator magnets, lapel pinbacks, greeting cards, and other products.

A counter-service restaurant called Blondie's opened at Universal Orlando's Islands of Adventure in May 1999, serving a traditional Dagwood-style sandwich.
