Apparently a new streaming TV channel through the Pluto TV app from Paramount will be non-stop Transformers episodes... starting from June 13th.
I don't know much about the app or if it is geo-locked to just US people, but if it has global access, it would allow people here as well to view episodes that may not be currently available from other streaming sites or youtube. The benefit is that it should be a free service, as it will have advertising inserted into the programs, while the only difference to other streaming/hosted sites is that you would probably be stuck with what ever the broadcast schedule is, and not be able to select the episodes or series yourself.
Welcome into the world of Transformers TV, a world where everything is…More Than Meets the Eye. A universe where shape-shifting, sentient robots in disguise hide in plain sight, and battle with the future of their world – and ours – at stake. Transformers TV will include series such as Transformers: Cyberverse, Transformers: Prime, Transformers: Robots in Disguise and many more all day, every day.
