TV's biggest programmers and broadcasters are turning to YouTube for help finding and engaging audiences. The latest to join in? Time Warner (TWX) and Walt Disney (DIS -0.55%).

On March 10, Machinima announced an $18 million financing round led by Warner. MK Capital and Redpoint Ventures also participated, along with Google's (GOOGL 1.42%) recently unveiled Google Capital arm. A day later, Recode's Peter Kafka reported that Disney is courting YouTube programming aggregator Maker Studios at what amounts to a $500 million valuation.  

Goodbye, remote. Hello, mouse.
Can investors expect more Disney and Warner content to show up on YouTube as a result of these deals? That's tougher to say, though in Warner's case, the studio talks as if Machinima will grow to be an important distribution partner.

"Machinima connects with a worldwide audience of millennial fans and creators," said Craig Hunegs, President, Business and Strategy, Warner Bros. Television Group, in a press release. "We're excited about the opportunity to work closely with Machinima and its channel partners to reach new audiences, create new original content, and discover new talent."

History backs up the bluster. Look at The CW, a joint venture with CBS that plays an increasingly important role in distributing Warner IP. Arrow, for example, which is based on characters sourced from Warner's DC Entertainment subsidiary.

Lower-tier networks such as Machinima on YouTube or The CW on broadcast TV are gaining importance because it's easier for these smaller-traffic destinations to cater to niches, which, in turn, makes them interesting to advertisers. What better way to reach your demographic than to advertise on the very network that caters specifically to their interests?
