Does RTE News Now provide separate content from the streamed RTE One news bulletins?
They have a few live bulletins, entertainment updates & film interviews, highlights from recent programmes (as you can see in WW Update's video) and a live relay of Euronews (including Raw Politics). Sometimes it shows sporting events that don't fit into the other channels' schedules. For those broadcasts they remove the news graphics.
More cooperation with Euronews might turn News Now into a much better channel. AFAIK RTÉ still owns part of Euronews.
