Regarding the news graphics, there certainly seems to be a culture or management at Seven News that likes to tweak graphics. And its largely to such a minor degree each time that it would have almost no impact on the viewing experience and perception of the news service. The only time there was a major change in the past few years was the introduction of the new news theme. The experience of that “fiasco” will probably mean that no-one at the network will dare try a big change again. I appreciate that viewers don’t generally like change, but it seems these minor changes are largely a wasted effort.
I recall joking in the past about getting 50 posts on the forum if the Sunrise clock font changed; I imagine this will be the same and in the end will have zero impact on the Seven News product because no-one outside this forum will notice .
