The game ticker template uses the Game's CentreCount count to decided whether to display the background or the info for the game, with the intent being that it displays the background until something happens, and then the news. Given that we always create CentreCounts for 1900 for every game, though, I suspect that it always displays news.
Game.news() also checks what CentreCounts we have for the game, and redirects to background() if the most recent is for 1900, so the check in the template is likely redundant
