I don't know what actually happened because I wasn't able to investigate while it was actually going on, but I was watching something I recorded on TiVo and my program was interrupted by a notice about a missing child. The screen was mostly blank and the notice was at the top. There was no sound. None of the buttons would work until it was over. The time of the notice, flashed on the screen, meant it was live. When the notice ended, I was "returned" to Live TV, meaning Channel 2 (on Spectrum, independent WAXN, virtual channel 64) which was showing "Elementary". Supposedly this aired on every station.
