BL is the most "mainstream" in its live action adaptations, to the point you get multiple countries adapting the same BL like picrel.
Anime is far more popular with men, and they'll recoil in horror at BL, but be okay with yuri. So, yuri tends to get more anime than BL. But live action dramas are far more popular with women, who are disinterested with yuri but enjoy BL. So, BL is more commonly adapted via live action. You decide whether appealing and being popular to a specific gender in multiple countries is considered mainstream.
