If anime isn't mainstream then what do you call Pokemon? It's the biggest franchise in history and has been showing daily episodes on children's TV for decades. Battle of the planets (Gachaman) was big in the 70s, Transformers and Voltron was big in the 80s and everyone knows the Toonami blocks of the 90s. Anime has been main stream for 50 years now.
Mainstream is something that is the public consciousness and the majority of people either like or at least are familiar with. None of the things you mentioned are with possibly Transformers and a large part of that would be due to the movies. I wager that if you'd ask a bunch of random people about these things whether they'd know what you were talking about or just have a vague idea of it.
