Are iCarly and VicTORious tv shows within tv shows?

We know they merged to make Sam & Cat, but when if they all were in the universe of another show?

     Sam & Cat was one of the first double spin offs in tv history, taking Sam from iCarly and Cat from VicTORious, and making them into their own show.  This means that the iCarly/VicTORious/Sam & Cat universe are all one universe.  It is sometimes referred to as the Schneiderverse, after the producer Dan Schneider who created each of the three, and has stuff like Pear Phones in each of them.  Drake and Josh exist in this universe, with the evidence that the show Drake and Josh that we know it in Nickelodeon was a reality tv show.  It was a self aware show that had an introduction for what the episode was about.

Drake and Josh intro before the episode starts.

But!  Helen from Drake and Josh became the principal in VicTORious!

More curiously, if Helen is a character from Drake and Josh, why do the characters from VicTORious call "Drake and Josh" a tv show?

     The most likely conclusion that makes sense is the fact that every character on Drake and Josh are playing themselves in a reality tv show.  This is why it is self aware, but also Helen can jump between shows.  Like Crazy Steve's short appearance in Sam & Cat's episode, #SuperPsycho.  But another tv show refers to Drake and Josh as a tv show.

Henry Danger - Tears Of The Jolly Beetle, they watch Drake and Josh on their Pear tv.

VicTORious - 1,000 Berry Balls, Andre working at Yotally Tugurt.

Henry Danger - Substitute Teacher, a Pear Pad is seen.

VicTORious  - Sleepover at Sikowitz's, Robbie has a Pear Pad.

Sam & Cat - #FavoriteShow, Sam has to explain to Cat that they can't use Pear Products on tv, they have to change them to Banana Products to avoid lawsuits.  Henry Danger is in the same universe as iCarly/VicTORious/Sam & Cat.

There is undeniable proof that Henry Danger and The Thundermans are also in the same universe, as there was a crossover episode filmed that is yet to air on Nickelodeon.  So what we have is the Drake and Josh/iCarly/VicTORious/Sam & Cat/Henry Danger/Thundermans Universe.

In an unexpected twist, The Thundermans is a tv show in 100 Things To Do Before High School.  The evidence goes that all of these shows are in the 100 Things universe as their own show.
