- Actor Allusion: See Celebrity Paradox.
- Tommy "The Nightmare" Smith, host of San Andreas' classic rock station K-DST, complains about the plaid-wearing grunge rockers featured on the modern rock station Radio X, which his own voice actor — Guns N' Roses vocalist Axl Rose — was famous for wearing himself in real life.
- Earlier in Lazlow's and Couzin Ed's real life radio careers, Lazlow was the sidekick of Couzin Ed, whom he would almost always tease on-air.
- In San Andreas, one of the callers in WCTR's "Area 53" segment complains about having been placed in solitary confinement for hacking, having the ability to "launch nuclear missiles just by whistling into a phone", but is now only using "[his] powers for good." The voice actor is the legendary Kevin Mitnick, once the most wanted hacker in America back in the mid-90s, who is now a computer security consultant after serving prison time.
- Casting Gag: Mike Whitely, one of the more notable radio announcers of IV's Weazel News, is voiced by an actual radio veteran, John Montone of CBS' New York City-based 1010 WINS AM (the originator of all-news radio).
- Defictionalization: Lazlow Jones, radio scriptwriter for most GTA games from III onwards, has an actual XM radio show, in large part because of his resurgent popularity stemming from his involvement with the series, including, but not limited to, hosting a radio show in each game. He directly references it in IV, when he uses lines about remembering a time "when 16-year-olds could drink, smoke at bars, listen to heavy metal, and get into high-speed accidents" which was lifted directly from the opening to his show.
- Fake Nationality: While the original incarnation of IV's Vladivostok FM plays mostly Russian music, its DJ, Ruslana Lyzhychko, is actually Ukrainian, and has even performed and won for that country at the 2004 Eurovision Song Contest. In fact, her winning song, "Wild Dances", is part of the original soundtrack.
- Keep Circulating the Tapes: Starting with Vice City, the games have been losing songs 10 years after their release.
- Name's the Same: Maurice Chavez and the titular host of Gardening With Maurice. Interestingly, Gardening with Maurice was mentioned in III. When Vice City introduced Maurice Chavez, common opinion was that he would go on to host Gardening With Maurice in III era, which was subsequently Jossed.
- Lampshaded to an extent when a caller phones Gardening with Maurice asking why everyone on the radio is called Maurice.
- Playing Gertrude: Discounting prequel games, the fictional version of himself Lazlow plays is actually older than he is in real life. The real-life Lazlow had just turned 40 when GTA V came out, while his in-game counterpart is 51.
- What Could Have Been: The game files provide evidence that plenty of songs were in the game at some point, possibly being cut due to legal issues, lack of space or just being placeholders. Some songs are likely cut due to other games being released around the same time licensing them first, as seen with "Sucker MC's" which was in Saints Row 2, or "Everybody Wants to Rule The World" being in BioShock Infinite.
