Due to the circumstances of [Tokyo MX parent company] Tokyo Metropolitan Television Broadcasting Corporation, further broadcasts of the Interspecies Reviewers on Tokyo MX will be suspended.
As mentioned above, late-night TV anime broadcasts are basically paid commercials from the production committee, and don’t directly bring in any money for the franchise.
AT-X for example, is owned by TV Tokyo, a much larger and higher-profile media organization than Tokyo MX, and DoCoMo and Amazon are larger still.
