Note that DSL/Fiber [1] AT&T, [2] Verizon Communications, [3] CenturyLink, [4] Frontier Communications, [5] Windstream and Satellite [6] HughesNet are not part of "the 13."
I see that [7] Charter Communications, [8] TWC and [9] Brighthouse have merged.
Finally, [10] Sparklight (Cable One), [11] RCN (Grande Communications & Patriot Media), [12] Wide Open West (WOW), and [13] Wave Broadband (acq by TPG) are not included in the blog article.
So, Canadian [14] Rogers Communications, [15] Shaw Communications, and [16] Videotron may become future, near-term targets, along with others.
