After an initial investment of $150 million, YouTube will spend another $200 million on new programming to more effectively market its nearly 100 channels featuring commercially produced videos. The company has also secured commitments from advertisers to run more than $150 million of ads on these channels this year.

Since YouTube is already the leading video destination on mobile networks, the investment can only increase its market share – while further multiplying mobile video traffic volume.
