Hulu and Google announced plans to offer bundled channel services, joining those launched by SlingTV, Sony’s Vue and, most recently, AT&T’s DirecTV Now. All offer many popular channels currently available from cable and satellite services like Comcast and Charter. The main difference is that they stream all the content from these channels over the internet.

These new bundled channel packages are meant to compete with cable or satellite, and some have called them “skinny bundles” under the assumption that they’ll have fewer channels and be cheaper. But that’s not necessarily the case.

So why would a viewer want to switch to these services? Why are they starting to saturate the market, and what do they mean for the future of television?
