Comcast

Comcast is what many American households run into when they need broadband, cable TV or a mobile plan from Xfinity. By our assessment, its real strength is scale: it bundles home internet, TV and mobile under a single big telecom brand, with Xfinity as the consumer face. The downside is that this sort of giant is rarely intimate, and customers often meet it through contracts, set-top boxes, router rentals and customer-service frustration rather than charm. In practice Comcast feels like infrastructure more than a friendly shop, which is why it can be hard to love even when it does the job. It sits among the largest US communications companies, and it is not the kind of provider that tries to be small or boutique.
