American TV stations frequently have computer and other equipment problems. The evening news can actually be fun to watch to see what will happen next. For example, on a local TV station here in Sacramento the anchors were talking and then all of a sudden the theme music of the station comes on AT FULL VOLUME! It lasted about 20 seconds. Odd photographs will come up at random too, they'll be talking about a murder case and the "live report" turns out to be video of a parade or something. Or the tape will suddenly grind to a halt. Or the microphone won't work. Or the live feed audio will crash unexpectedly.
The reporters and anchors are usually left holding the bag, trying to explain why video of a "terrorist attack" was actually that of the Rose Parade, or why a still photo of a hand grating a block of cheese suddenly popped up from nowhere in the middle of the newscast. It's similar to what one might find on a state run newscast from the Third World. Station equipment is usually paid for through ad revenues, which means that maintenance can be lacking, or that the equipment is ancient, especially in minor markets.
Many US TV stations still use live cameras from the 1980s that run Betamax tapes. Only a handful of stations have upgraded equipment to be fully HDTV compatible. The cost can be enormous-KCRA in Sacramento plunked down nearly $10 million to convert. Usually for a market Sacramento's size (2 million people) the expense simply isn't worth it, but KCRA has a long tradition dating back to when they were owned by the Kelly family in the 50s, 60s, and 70s of bring an innovator. The Kelly-owned KCRA was the first inland TV station to have all color news, in 1962. They had the first news helicopter not based in SF or LA in the west. KCRA had a digital signal on the air when only 1% of Sacramentans could receive it. So the new owners, Hearst Corp, were willing to plunk down the dough.
