Investors Business Daily: Viacom’s 9% drop in fiscal Q3 U.S. ad revenue due to a decline in ratings added to fears that traditional media and cable firms are losing the battle against Netflix and Amazon. Earlier in the week, Disney sparked the media stock sell-off after saying ESPN has lost a “modest” number of subscribers and trimming its guidance for cable operating income growth. Shares of Netflix rose 2.2% for the third straight record close on the stock market Thursday.
