Hyperbole aside, you are conflating two things: The accuracy of breaking news with the dissemination of that news. Breaking news is very often inaccurate. No amount of fact checking can fix it because in most cases no other news is available to counter the initial report. Unless you have reporters on the ground who can provide a more accurate report, you can't hope to improve that report. When a later report becomes available it becomes the newest report.
Like Infobitt, you appear to be aiming for a metric of quality ("accuracy") that the market doesn't care about that much. Take the recent plane crash in Taiwan as an example. At first it was reported that there were one or two casualties. Later reports said 13 dead. Most people are like "Oh really?" But, even though the first report is less accurate, it has more value to people than the second (unless you have family on the plane).
As for the distribution of news, unless you are Facebook you have no control over how news is shared. In fact, most people don't care about the casualties, they just want to share the video of the plane crashing across the bridge.
News spreads however it's first reported. Sometimes it's corrected later, but often times it's picked up and spread, even by major news organizations. You are assuming that news will eventually be corrected by news organizations. First, that's a false assumption (https://news.ycombinator.com/item?id=8757421), and second, for many it's already too late by that point.
An anecdote of one false rumor not mattering doesn't change the fact that accurate news makes a difference.
