My tips in concept- (but I might be wrong. )
Something coming to my mind, what about fish triangle
triangle means play button. fish of three triangles might mean moving fish/ moving news/ live/ dynamic
it doesnt have to be the fish that you can tell immediately, but ppl can feel. Just like "Fedex" logo
the three triangles can moving forward or back, making the logo has unlimited possibilities of look but keep it under same system....
