The McGuinness Experiment

The McGuinness Experiment was Matt's main channel from 2017 until 2021, now delegated to secondary channel status indefinitely. Standard uploads would include Sonic content, as Matt's attempts to move away from the subject butchered his analytics. The channel was closed in 2021 to coincide with the beginning of The Show, and is a running joke throughout the narrative.

In-Universe
Matt created the channel under the influence of Him Upstairs. As the name implies, the channel was an experiment: an experimental channel for Matt to make things before deciding how to properly pursue YouTube, something he'd wanted to do since 2008. The channel is incredibly rough around the edges, a deliberate stylistic choice, and had contributions from many other YouTubers in the Sonic community, particularly on the show Matt Reviews.

In Reality
TME was planned from the start as the opening act to The Show and conceived in 2016. As such, many ideas that would be picked up later down the line were introduced here. Reggie segments, a review series and several in-jokes and running gags interspersed throughout the TME videos were all foreshadowing of what was to come. It also gave other friends of Matt their big break who would be major players in The Show, such as Frazoid.

The abandonment of TME was the result of Matt deciding it was time to initiate The Show, though this was not stated publicly. TME was officially closed in May of 2021, though it may re-open at any time.
