Billionfold, Inc.

Background

Billionfold, Inc. is the production company of Butch Hartman, creator of the Nickelodeon shows, The Fairly OddParents, Danny Phantom, T.U.F.F. Puppy, and Bunsen is a Beast, including the YouTube webseries, HobbyKids Adventures. Hartman didn't use his own logo until 2004, when Danny Phantom debuted. On February 8, 2018, Hartman announced on his Twitter and YouTube accounts that he had left Nickelodeon as of February 2nd after his 20-year run on the network, resulting in Bunsen is a Beast, his last show for the network, being cancelled two days later. In February 2021, however, it was announced that Hartman would be returning to Nickelodeon as a producer of a live-action/animated reboot of The Fairly OddParents titled The Fairly OddParents: Fairly Odder, which premiered on Paramount+ on March 31, 2022. However, the series was later removed from the streaming service and Nickelodeon's official website that following January, presumably due to the failure of the series.

(April 3, 2004-March 31, 2022)

The 4:3 version
The 16:9 version

Logo: On a plain white background with a light teal trapezoid shape, we see a drawing of Butch Hartman as a superhero, wearing a suit that's somewhat similar to Superman's, but purple with black briefs, yellow boots and a cursive red "B" in front of a yellow circle where the "S" is supposed to go. Butch's cape extends out to reveal the words "BILLIONFOLD INC." written on it.

Variants:

On Butch Hartman's video of the Nicktoons Unite parody trailer to the 2017 film Justice League, the logo is modified with Butch wearing a different suit, in a style of Superman's suit from the DC Extended Universe films. Also, the background is black, and the trapezoid shape is absent.
A true 16:9 version exists.

Technique: 2D animation by Rough Draft Korea.

Music/Sounds: A loud "heroic" fanfare (composed by Guy Moon, who did the score for all four of Hartman's shows) accompanied by a chorus loudly singing "BILLIONFOLD!", followed by a Road Runner-like voice uttering "inc!"

Music/Sounds Variants:

On seasons 2-3 of Danny Phantom, the logo's audio plays with the end credits theme.
On The Fairly OddParents episode, "Open Wide & Say Ahhh/Odd Pirates" and A Fairly Odd Movie: Grow Up, Timmy Turner!, the ending theme of the show/movie respectively plays over it. Oddly enough, the Latin American Spanish dub of the former actually had the logo's audio, implying the former's case is a post-production error that made it to the broadcast copy.
On a French iTunes print of the Danny Phantom episode "Memory Blank" (S02E01), the audio is slightly high toned.
Similarly, on the iTunes France print of the said show's episodes "The Ultimate Enemy, Parts 1 and 2", the audio is low pitched.
On 2009-2014 airings of Season 6 and later episodes of The Fairly OddParents and Danny Phantom with the split-screen credits, later episodes of Bunsen Is a Beast! episodes with the 2017 Nickelodeon Productions logo and The Fairly OddParents: Fairly Odder, the "Inc!" sound effect has been removed.
On the Arabic dub of The Fairly OddParents: Fairly Odder, the chorus was absent.
Also on the last shown video source, the voice-over was absent and it was sped up.

Availability: First introduced with Danny Phantom and later incorporated onto episodes of The Fairly OddParents beginning with season 6. Also appeared on T.U.F.F. Puppy, the Fairly Odd Movie trilogy, the Nicktoons Unite parody trailer to the 2017 film Justice League, Bunsen Is a Beast!, HobbyKids Adventures, and The Fairly OddParents: Fairly Odder.

Legacy: This is a well-known logo among fans of Butch Hartman's works, though the controversies involving Hartman have tainted the logo for some.
