EasyDeskTicker displays RSS news feeds, stock quotes or custom messages as a flicker-free ticker bar on the desktop.
It docks to the top or bottom of the screen and displays news as a scrolling line, as known from TV stations.
Headlines are constantly updated, one click and the full article is opened in your web browser.
The program is highly customizable: rss feeds, fonts, sizes, colors, speed, position and more!
It optionally stays above other windows or can resize the desktop, so that no other application is overlapped.
Custom messages can be easily configured, either with a simple plain text file or by directly typing your messages into a text box.
So EasyDeskTicker can be used for advertising in a shop window, either full screen or together with any other application (e.g. powerpoint presentation).
It can simply be used in a company to keep the personnel informed via intranet. Just place a plain text file with your headlines in the network.
