Welcome to WebmasterWorld, Theordore :)
There are few things that might explain this, but perhaps the most likely is that Google simply hasn't revisited your site since you made the change. You can estimate the last visit time by clicking on the "cached" link in search results next to your listing or directly searching for cache:www.example.com/URL
While Google is pretty fast at visiting some things, it also assigns "crawl budget" as it believes is appropriate, so if you have a site without many links that does not change frequently, Google may have a slow schedule for you. If you're the BBC news, Google is visiting pretty much constantly.
If that date in the cache is after you made the change, report back and we can look at other possibilities.
