Here's a typical way the local news channels tease you to keep watching. A co-worker told me a story of how he used to work at a fast food restaurant. One time he found a diamond ring and returned it to its rightful owner. A local news crew came and interviewed him, so he decided to watch their broadcast. At the commercial break before his interview the news anchor said 'A diamond ring was found at a local restaurant, but was it returned to its rightful owner?' All during the commercials my friend was wondering if he had given the ring to the wrong person. When the article actually aired not one word was mentioned about the ring being given to the wrong person.
IMHO, local news broadcasts are entertainment similar to a sitcom. Just not as interesting.
