Michael Wolf: What's Next for Tech and Media in 2018

Alphabet Inc., Facebook Inc., Amazon.com Inc., Apple Inc. and others are hunting for new areas of growth--often on each other's turf--as they enjoy soaring revenues and stock prices. They are poised to bump into each other across the board, in online sports viewing, movies, news and even podcasting. Up for grabs is an extra $300 billion a year in revenues that Activate projects will flow into the $1.7 trillion global consumer media and internet market by 2021, through growing internet-access fees, ads and paid content. Activate estimates the market will grow 4.1% a year. Consumers' time, though, is already stretched, with young people in particular tethered to devices much of the day.
