Sony's new PlayStation Vue television service probably won't save you money over cable.

Starting at $50 a month, Vue offers more than 50 over-the-air and cable channels for online streaming. But you need a PlayStation game console and you still need Internet access — likely from the same cable company you're trying to ditch. If you press, your pay-TV company might offer a slimmed-down TV package that's comparable to Sony's in price and lineup.

Would you pay to see some of the Internet's best video clips first? Vessel, a new service trying to change the way that short video pieces make money on the Internet and mobile devices, is betting on it.

Instead of free-for-all distribution supported solely by advertising, Vessel will charge $3 per month for exclusive early access to clips of musicians, sporting events, comedians and many other forms of entertainment not available on YouTube or any other digital video service for at least three days. CEO Jason Kilar, formerly head of Hulu Plus, believes Vessel's model will be able to pay video producers about $50 per 1,000 views of their clips on the site. That compares with just $2.20 per 1,000 views of ad-supported video at sites such as YouTube, Kilar says.
