Telly offers free dual-screen smart TVs in exchange for ads.

Telly, a startup led by a co-founder of Pluto TV, is offering its first 500,000 mass-produced dual-screen smart TV sets for free to consumers when they start shipping this summer. The 55-inch sets, which have 4K HDR picture quality and a built-in premium sound bar, would retail for more than $1,000. Telly is bringing to market the first dual-screen smart TV, with a smaller screen below the main panel that displays sports scores, news, weather, display ads, and other supplemental information. The free giveaway is an effort to upend the prevailing business model in streaming and have advertising more completely fund the device itself.
