In a few more days we will be saying goodbye to the '2010s so let's do a giant retrospect! This thread will contain a lot of irrelevant or non-Bratz dolls but I'm putting this in the Bratz category as an exception since they're mentioned. I know this is random as hell but I wanted to just type whatever was in my mind so please don't hurt me djfkdsj. Obviously this is not perfect and is missing a lot so of course, add what needs to be added as we need people to chime in this flopping forum r.i.p. Here we go:
WARNING: This is very long
2010:
Freaky just got fabulous as Monster high hits the shelves:
These type of music videos start becoming more popular for dolls:
Barbie had a great 50th birthday celebration last year while Bratz were "away" but now our girls are now back!
The (now more appreciated) comeback is marketed as their 10th anniversary (logically 9th).

This false hope:
Moxie Girlz!

MGA also releases the iconic Moxie Teenz. Companion line to "Moxie Girlz" + to compete with Liv! They would soon be discontinued around 2013.
On the side:
*Lalaloopsy made their debut in July as well!
*Mattel relaunches Polly Pocket.
*My Scene is on the edge of dying.
2011:
Barbie is living her glam era and MH is growing while our girls are continuing their 2nd year in their 2nd decade.
Remember when Masquerade flicked off conspiracy theorists? These things were also applied to for example Monster high and Bratzillaz as well.

My Scene finally has their farewell before their 10th anniversary:



2012:
MGA is applying feedback from fans which sales then start going up!:

Bratzacadabra! Bratzillaz (wicked cousins of the Bratz) and Novi Stars come and cause a commotion. Also, I'm gonna include MVs just to show y'all what I meant in for 2010.
Did I mention that dolls also now had webisodes? MH, Bratzillaz, and Novi Stars had them which as we can see, "storylines" now become prominently more focused within doll lines.
Mattel then applies this to Barbie with the iconic show "Life In The Dreamhouse" (the one and only, not Dreamhouse Adventures).
Some say this year is MH's peak. Their fanbase is big at this point and also, they now have featured films!

The theme of monsters/dark creatures/etc.
in doll lines continue to grow after MH.Bratzillaz/NS. Playhut transfer the characters (or borrows the names) of MystiKats (from the 00s) for Mystixx Vampires.
On the side:
*Liv releases their last 2 lines (note their removed articulation) and officially discontinues from low sales. Spin Master eventually replaces them with La Dee Da and Kawaii Crush.

*Sparkle Girlz finally come in around this time. We stan Walmart cone queens ❤.
*Cutie Pops! The original CookieSwirlC Lotta Looks doll.
2013:
IMO just like how the pop girls were releasing this year (Gags, Brit, Bey, Katy, Miley, etc.), I thought this was a fun time!
Our girls are now tall and have a pizza hut logo which obviously was not the tea for many. I still love this era though don't judge me:



Bratzillaz's name changes to House of Witchez to differentiate themselves from MH.
There are now finally dolls for Barbie's LITD show:
Mattel starts releasing webisodes for the missed opportunity fairy-tale theme spin-off of MH, Ever After High. The dolls would be found at Justice that July.
Remember Genie Magic?

Fairy-tale themed dolls also now appear as seen with Fairy Tale High + Once Upon A Zombie. Both with attempted webisodes, however, OUAZ goes on to release novels.
