"[3] Another World focused less on the conventional drama of domestic life as seen in other soap operas, and more on exotic melodrama between families of different classes and philosophies.

It was the first soap opera to do a crossover, with the character of Mike Bauer from Guiding Light, which was also created by Irna Phillips, coming from Springfield to Bay City.

[6] On November 22, 1963, a group of executives (including Executive producer Allen M. Potter and director Tom Donovan) met at the VMLY&R ad agency in New York to discuss the show's opening story, the death of William Matthews, when they heard the news of another death in Dallas: the assassination of President Kennedy.

[7] After opening with a death in the core Matthews family, Irna planned to follow up with an out-of-wedlock pregnancy, a septic abortion, a shooting, and a murder trial.

"[9] On April 12, 1999, as part of a shakeup of the network's daytime and early morning schedules (in which NBC also canceled NBC News at Sunrise (with newcomer Early Today replacing it as the network's early-morning newscast) and picked up the daytime talk show Later Today (a short-lived spinoff of Today) in exchange for the withdrawal of the talk show Leeza (which was renewed for the 1999–2000 season and subsequently sold into first-run syndication) from the network's schedule), NBC announced that it would not renew Another World, ending the series' run after 35 years once the show's previous renewal agreement ended that June.

Independent station KICU-TV picked up the show and aired it for the rest of its run (with NBC logo bugs and end-credit vocal network promotions removed), but the series still experienced a steep ratings decline in the Bay Area market as KRON refused to guide viewers to the program's new home.

A "viewer-directed," text-based continuation of the series called Another World Today existed online, initially sanctioned by TeleNext Media, the production arm of Procter & Gamble.

Many well-known film and television actors and celebrities appeared on Another World early in their careers: Others who were dayplayers or extras included: Dan Futterman, Zach Grenier, Melissa Joan Hart, Frankie Muniz, Donna Pescow, Reginald VelJohnson, and Ming-Na Wen.
