Hey so I thought this could be fun. I love the idea that Ticker programs have funny clever names and apply to a variety of knowledge skills, subjects or things.
To get it us started off I'll post some of my favorites
This one is probably my best
Measure of a Johnson: applies to Johnsons, their specialties and rating. I also figured the Rate My Johnson Ticker was about something else

Narcono: Drug info, Prices, Quality Assurance
Shiawase Seer: News, People, and Products related to Shiawase
Shadow Spotter: Shadow Runner info, Specialties, Ratings
FireWatcher: Ares News, People, Products
Lone Star Reporter: News, Procedures and People
I have more but I really want to see what other people create. Remember Tickers are usually free or cheap but have a way of distributing news to those people who care about that subject.
This is really more for fun and flavor than anything else

Here's the description from Data Trails
Ticker: A series of commlink apps that provide an information feed from a specified source, the vast majority being legitimate, such as stock markets and news organizations. Some shadow services also use these apps to give details on other shadowrunners, fixers, Mr. Johnsons, police response times, and current payment rates for a variety of services and bribes. Ticker reduces the time for subject-related Matrix Searches in half. Obviously, there are a great many topics out there that don’t generate enough traffic to merit an information feed—for example, you can’t subscribe to a feed with up-to-the-minute news about Medieval Europe when Mr. Johnson sends you after a weird-looking cup and expect results to come flooding in.
