7 Kid Pix
8 My Scene
Mattel's short-lived answer to Bratz that somehow got 3 movies to its name.
9 Plug-and-Play TV Games
These were very big back in the mid-2000's. We had a Pac-Man one, a Nicktoons one, a Scooby-Doo one, and (I believe) a Fantastic Four one all from Jakks-Pacific. I think I still have the Pac-Man and Nicktoons ones somewhere.
10 Oregon Trail
The Contenders

I'm talking about the obscure personal media player from the mid-2000's.

21 HD-DVDs
A failed format which was a competitor to Blu-Ray Disc
Hilariously enough there have been a few HD-DVD/Blu-Ray combo players though
22 View-Master
I think we've all used one at least once in our lives. This would be an interesting topic to talk about as almost every piece of media used to have at least one reel made out of it just for the machine.
23 The Wonder Girls
Yes, there's actually a TV movie based on the South Korean K-pop girl group of the same name and it aired on Teennick out of all places. Sure, it was made in 2012 but it would make for a perfect "X was weird" video on.
24 E-Kara
Takara's fully-fledged karaoke system aimed at children which used cartridges
It was released in the US by Hasbro and flopped there but it was more popular in Japan because obvious reasons.
25 Transformers: Energon
This and Cybertron were the first two Transformers series I remember watching.
