More wild roller coaster stock-market action over the last few days -- ending with big declines on Friday -- had media-related companies virtually flat for the week.

Many of these wild swings were thanks to Donald Trump's overall economic threats of major tariffs targeted at China.

For the week, Dow Jones U.S. Broadcasting & Entertainment Index was down 0.15% for 1,203.55, while Dow Jones U.S. Media Index sank 0.4% to 810.52. In Friday results, indexes declined 1.4% -- down around 9% from the late January highs.

The bigger Dow Jones Industrial index lost 0.7% to 23,960 over the last five days. On Friday, the index had a sharp decline of 2.34%, or 572 points.

Key digital media companies -- so-called FANG (Facebook, Amazon, Netflix, and Google) stocks -- were hit a bit harder than most on Friday. Facebook was down 1.3% to $157.20, while Amazon lost 3.2% to $1,405.22, Netflix slipped 1.8% to $288.76, and Google (Alphabet), gave up 2.2% to $1,009.95.

Among other digital media platforms, Twitter was down 1.9% to $28.10, while Snap lost 1% to 14.25.

A core group of traditional media stocks fared a bit better: AMC Networks was virtually flat, down 0.02% to $51.67; CBS slipped 0.04% to $52.86; and Discovery lost 0.04% to $22.62.

The bigger losers included Dish Network, which saw a 2.4% drop at $38.50; Charter Communications, losing 2% to $310.67; and Tronc, the TV station/newspaper group, giving up 2.9% to $15.95.

Comcast was down 1.4% to $34.11, while Walt Disney lost 1.7% to $100.36 and 21st Century Fox gave up 1.8% to $35.69.

Some stocks gained: Viacom -- which was down for the week due to its tussle with CBS over a potential merger -- recovered somewhat, up 0.5% to to $30.91.

Sinclair Broadcast Group, which received criticism for airing a company-wide promo about "fake news," inched up 0.3% to $29.95 on Friday --- but was down 4.3% for the week.

Among other TV station groups, Nexstar Media Group grew 0.9% to $65.25, while Tribune Media slipped 0.07% to $40.25 and Tegna sank 1% to $10.96.
