If you were born prior to 1973, then the first thing that comes to mind when you hear this word is probably Hoss and Little Joe. This most popular of TV westerns was certainly a bonanza for NBC as it ran for 14 years. So what’s a bonanza? A large amount of something positive, or something very valuable, worthwhile or profitable. Who doesn’t want one of those?
Example: Jennifer’s long-time friendship with her junior high soccer teammate miraculously ended up being a bonanza for her interior design career when Vicky hired Jennifer to be the designer of record for her nationwide chain of popular yogurt shops.
