Jell-O's early advertising campaign, initially directed by William E. Humelbaugh and later Frank LaBounty, first appeared in the ''[[Ladies' Home Journal]]'' in 1904. The print ads were often accompanied by recipes and color illustrations and became very popular. Artists such as [[Rose O'Neill]], [[Maxfield Parrish]], [[Coles Phillips]], [[Norman Rockwell]], Linn Ball, and Angus MacDonall contributed to the campaign. Franklin King, working for ad agency Dauchy Company, depicted his daughter Elizabeth in many of the illustrations, making her the recognizable "Jell-O Girl".<ref name="timeline"></ref>

[[Jack Benny]]'s top-rated radio program began its Jell-O sponsorship in 1934.<ref name="timeline"></ref> The show did not break for commercials; instead, announcer Don Wilson incorporated speeches about Jell-O into the program at appropriate places, to Jack's feigned comic annoyance. The first show originated the five-note "J-E-L-L-O!" jingle retained in Jell-O's later advertising. [[Lucille Ball]]'s ''[[My Favorite Husband]]'', the radio predecessor to TV's ''[[I Love Lucy]]'', was another popular program sponsored by Jell-O for much of its 124-episode run, beginning January 7, 1949. Ball's character Liz Cooper often opened the program with the lively greeting, "Jell-O, everybody!"

Comedian [[Bill Cosby]] is associated with Jell-O and, more famously, Jell-O pudding, and he appeared in many commercials promoting both. Later shows like ''[[Mad TV]]'', ''[[The Simpsons]]'' and ''[[Saturday Night Live]]'' parody Cosby, using Jell-O references like "pudding pop".  In the 1960s, the cast of the sitcom ''[[Hogan's Heroes]]'' did a commercial with [[Carol Channing]] featuring Colonel Hogan, his men, Kommandant Klink and Sergeant Shultz having Jell-O and Dream Whip for dessert. Also, in the first few seasons of the first of Lucille Ball's two 1960s television series, ''[[The Lucy Show]]'', cast members including Vivian Vance often did commercials for Jell-O.

In 1995, Jell-O carried the tagline "It's alive!" and had the phrase "J-E-L-L-OOOOOOO!".

In August 2018, Jell-O released an [[animated series]] on [[YouTube]] and [[Amazon Video|Amazon Prime Video]] titled "JELL-O Wobz" in partnership with [[DreamWorksTV (YouTube channel)|DreamWorksTV]].<ref>{{cite news|url=https://www.marketingdive.com/news/jell-o-teams-with-dreamworkstv-on-animated-series-for-youtube-amazon-prime/529246/|title=Jell-O teams with DreamworksTV on animated series for YouTube, Amazon Prime Video|work=Marketing Dive|access-date=August 6, 2018|archive-url=https://web.archive.org/web/20180806145724/https://www.marketingdive.com/news/jell-o-teams-with-dreamworkstv-on-animated-series-for-youtube-amazon-prime/529246/|archive-date=August 6, 2018|url-status=live}}</ref>

In 2023, Dessert brand Jell-O updated the brand design for the first time in a decade, making it more playful.  The logo became bolder and blockier, and hyper-realistic images of pudding and jelly fruit appeared.<ref>{{cite web |title=Dezeen – Playful Jell-O rebrand  |url=https://www.dezeen.com/2023/08/09/brandopus-jell-o-rebrand/ |access-date=September 10, 2024 |website= dezeen.com |date=August 9, 2023 }}</ref>
