Keeping up with trends

I know they have been around a while but Air Fryers appear to be the latest must have kitchen gadget.   Whilst cooking tea the other night I noticed that the cooking instructions now included timings for air-fryers.

It got me thinking about the impact of the trend on food manufacturers and the thought process they will have gone through.  Did they wait until they needed to re-print their packaging to make the change or did they decide to keep on top of changing consumer needs and update all packaging at a cost to the business?

Q.  What changes in another industry could have a knock on effect on your business?
