AT&T (T - Get Report) is looking to buy Time Warner (TWX for $85 billion. But the Department of Justice is trying to block the deal to limit concentration in the media space. The deal is headed to trial in Washington DC - some 17 months after AT&T first announced the deal back on October 22, 2016.

How have the stocks of both companies performed over this period?

AT&T is down just under 1%.

Time Warner is up 8%.

The S&P 500 is up 28%

The uncertainty over this deal has kept share prices for both companies on a tight leash.

By acquiring Time Warner, AT&T is better positioned to compete with Netflix (NFLX - Get Report) . Time Warner owns HBO and other premium content channels.
