Google's fast-growing YouTube turned 7 on Monday. The world's most popular video-sharing website has come a long way already, but there are few things that can turn YouTube into a monster moneymaker for the world's most valuable Internet company.

Television may be evil, but it's not evil enough for Wall Street. Analysts are worried that ratings for Viacom's children's TV leader Nickelodeon are in danger over its friendly streaming video deal with Netflix.

Sirius XM Radio raised its prices in January and totally got away with it. Last summer, Netflix tried it and got burned. So what did the satellite radio giant do smarter than the streaming video king?

There were a few positives in Netflix's quarterly report Tuesday, but the stock fell 14% thanks in part to mixed results and uninspiring guidance. But the real reasons investors fled are more complex -- and disturbing.

Netflix posted reasonable results Monday, but the video service giant's stock took a big hit due to weak revenue guidance. Concerns about Netflix may be valid, but let's look more deeply at what it revealed in its quarterly report.

When "Mad Men" came back to AMC after a long break, the 1960s ad executives saw a 20% spike in ratings, and the reason why is as clear as a dry martini: Millions of viewers have streamed the first four seasons on Netflix.

There's no point in letting a $1 billion lawsuit get in the way of a good thing. Even though Viacom and Google's YouTube are still embroiled in a five-year legal tussle over video clips, the two are hooking up in a digital streaming deal.

Don't be surprised if Netflix subscribers are on cinematic binges right now. Many of the most popular movies available via its streaming service will be going away on Thursday when its deal with Starz expires and roughly 1,000 movies go offline.

Once upon a time, Amazon.com loved moms. Its free "Amazon Mom" service offered the same free two-day shipping as Amazon Prime, plus heaps of extra benefits for anyone who thought to ask for them (even dads and cousins.) But no more: Mothers' day is over at Amazon.

DVDs -- and even their more modern Blu-ray siblings -- are gradually fading to black, as VHS and LaserDisc did before them. Movie studios have seen this coming for some time. Problem is, it's part of a bigger trend they may not be able to overcome.
