I hate it that all cable turns to infomercials at 4:00am.
broadcast tv turns to infomercials after midnight and sometimes even by noon on weekends.
Radio stations do this too - during the tornados/floods here in the midwest, many “local” stations or what I thought were local stations, just punted and played green-tea and bowel cleansing info-mercials. The ones that ran with it really helped out, because the power was out in some locales and so the best way for information (or at least the only way) to be put out was through battery operated radios.
