Global media CEOs need a Xanax more than CEOs from other industries, with 75% of the former worrying "intensely about shifts in consumer behavior," versus only 50% of the latter, writes Jill Goldsmith. That's according to PricewaterhouseCoopers research presented at the World Economic Forum. Again varying from the norm, "a disproportionate 84% of [media CEOs] anticipate changing their company's strategy within the next year," and "over 60% of showbiz CEOs are concerned about the speed of technological change, 19% above the global cross-industry total."
