Sezmi is making its broadband and broadcast set-top setup available in 10 new markets, expanding beyond a limited trial of services in Los Angeles that began earlier this year. But while the company called its LA trial a success, we’re skeptical that consumers will be eager to pay $299 plus an additional $4.99 per month to get live access to content, most of which is readily available through Hulu or can be picked up over the air with a $30 digital antenna. Residents of Boston; Detroit; Houston; Kansas City, Mo.; Phoenix; Portland, Ore.; Miami, Orlando and Ft. Lauderdale, Fla.; and San Francisco will now be able to use the Sezmi hardware to get live and on-demand content from broadcasters like ABC, CBS, Fox and NBC, as well as broadband Internet video from YouTube and other online video providers. But unlike in LA, the system won’t be sold in Best Buy stores (though it will be on sale through bestbuy.com), and users won’t have access to certain premium cable content.
