AT&T's $85.4-billion bid to buy Time Warner is now official, facing what's expected to be a tough regulatory review, given the reach and impact of the telecom and the media behemoths.
The deal is a large one for both spaces, though each has seen a fair amount of reshuffling in the power rankings over the years. (In fact, both AT&T and Time Warner are themselves results of consolidation and spin-offs.)
The latest in this year's leadup was Verizon's bid to buy Yahoo to combine its Internet assets with the telco's earlier purchase of AOL. It's a race to reach as many users — and advertisers — with as much content as possible.
