Smosh Productions

Background
Smosh Productions (also known as Smosh, LLC) is an American production company founded by Anthony Padilla in 2002 and originally made flash animations for Newgrounds. His friend Ian Hecox later joined him and the duo started making YouTube videos three years later. They are one of the first channels on the site to ever exist.

Currently, they own the standard YouTube channel, Smosh Pit, Smosh Games, and formerly Shut Up! Cartoons. All of their brands are currently properties of Rhett & Link's Mythical Entertainment after being dropped by Defy Media when the latter company's assets were liquidated on November 6, 2018.

The name originates from when one of Anthony's friends, Ryan, had mistakenly said "smosh pit" instead of "mosh pit". In 2017, Padilla left Smosh to pursue his own YouTube career.

1st Logo (June 7-September 24, 2006)
Logo: On a white background in a narrow letterbox format, we see a double forward arrow sign ">>" with a lowercase "s" sandwiched in between. The camera then pans out a bit while the insignia backs up to the left side of the screen before propelling forward to the right, revealing the company name. After a few seconds, the letterbox closes.

Technique: The insignia panning and revealing the name. It was probably made with Adobe After Effects.

Music/Sounds: A random sounder or one-liner (which varies depending on the video), before Ian Hecox interrupts shouting "Shut up!!!".

Music/Sounds Variants
 * The California Stereotype Experiment: A soft rock tune with males singing "Californiaaaaaa! (Californiaaaaaa!)".
 * Boxman: A lighthearted ukulele rendition of "Twinkle Twinkle Little Star" plays while a baby giggles.
 * Stranded: Seagulls chirping.
 * The Best Car EVER: The sound of a car revving.

Availability: Can be seen on 2006 shorts on the Smosh YouTube channel.

Legacy: It's a funny logo, and is a favorite among fans of the channel.

2nd Logo (October 4, 2006-March 6, 2009)
Logo:Same as the previous logo, but the insignia is larger and zooms out from the camera before hitting the background (making a visible cloud), and the animation is smoother.

Variant: Starting with Hardcore Max, the logo's background is a /white checkerboard pattern filled with tiny Smosh insignias. Also, the URL appears below and a "TM" bug appears next to the company name.

Technique: Same as before, but with the additional SFX.

Music/Sounds: Same as before. On Ian's Birthday and Santa is Real!, Ian shouts the line less effectively.

Music/Sounds Variants: See this page. From How Not to Make a First Impression, up to New Year's Eve PSA, the logo is silent.

Availability: Can be seen on earlier shorts from 2006 to 2009 on the Smosh YouTube channel.

3rd Logo (March 6, 2009-September 6, 2017)
Logo: On a light blue background, two large pieces of cardboard appear. One piece is whole and appears from the bottom, while the other appears from the top and has the word "SMOSH" cut out of it into it in an stencil font. A spray can appears and sprays its respective colored paint onto the cardboard. When it's finished, the piece with the name etched in is removed to reveal the initial piece, which has the company name in sprayed onto it now. A "TM" bug appears next to the "H" while the "M" starts leaking a bit. A green forward arrow flips in from the right and places itself next to the company name, which expands to reveal the insignia like before. The text ".COM" pops up letter-by-letter under it. A few seconds later, the logo closes like before.

Variants:
 * On SMOSH: The Movie and various announcement videos on the company's YouTube channel, the logo starts at the "Shut UP!!!" voice clip.
 * On a few videos, the animation looks noticeably smoother.
 * On IF APPS WERE REAL, the animation is in delayed motion.
 * There's a 10th Anniversary variant that starts with a sped up version of the logo before the logo moves down offscreen revealing "S10SH" (along with the insignia) in a white psuedo-3D font with a black outline. The numbers turn to one-by-one, syncing with the usual slogan. It closes like usual.
 * On a few shorts from 2009/2010, the text "SHORT" (made to look like it was stamped onto the screen) appears over the text at the end.

Technique: The cardboard pieces appearing, the spray-painting, and the insignia flipping into place. Nice animation made in Adobe After Effects. It is worth noting that even though the "O" cut out from the cardboard has a line across the middle to keep the hole intact, The spray-painted "O" on the cardboard is fully intact with no line.

Music/Sounds: Same as before.

Music/Sounds Variants: See Logo Variations.

Availability: Common. While no longer current, it's seen on all of their videos from the era, starting with That Damn Prison Break (appearing after the 2nd logo) and ending with ONE LETTER OFF KIDS SHOWS. It also appears on shorts from the company on their YouTube channel as well as announcement videos and SMOSH: The Movie.

Final Note: Starting in 2017, Smosh no longer uses an intro for their skits, likely due to Padilla's departure.
