Spending the extra time and effort to make communication interesting and memorable usually seems like a waste, especially in business when you have lots of info to convey and it's always different. If the business punishes you for spending 8 hours getting a 1 hour presentation ready, then of course you're going to get it done in 2 hours and forget about making it interesting.
