Brits take over U.S media

• Lewis, a former journalist turned media executive who has served as CEO of Wall Street Journal parent Dow Jones and editor of The Daily Telegraph, will be tasked with making the company profitable again and elevating employee morale following a difficult year.

Between the lines: In August, Warner Bros. Discovery announced that former New York Times and BBC executive Mark Thompson would lead CNN as the network's new worldwide chairman and CEO.

• Reviews of Thompson so far inside CNN have been positive. Thompson replaced Chris Licht, who was fired in June.
• Like Lewis, his appointment ends a period of uncertainty at the company, and brings new leadership to the network at a critical time.

Be smart: Early reviews of Emma Tucker, who became the first female editor-in-chief of The Wall Street Journal less than a year ago, have also been good.

• Like Lewis, Tucker was an alum of another Murdoch-owned newspaper, having previously served as top editor at The Sunday Times.

What to watch: Whether the British leadership will bring the sense of metabolism and grit often associated with the U.K. media to three of America’s most powerful legacy newsrooms.

• Already, Tucker has reportedly wondered, "What do they all do all day?" when remarking about her new American colleagues.
