U.S. broadband has been one of the fastest-growing segments in the telecom industry for the past few years, but ACG Research's Michael Kennedy argues that it has "reached the end of its growth phase" in a FierceTelecom article. Kennedy says the industry should now take steps to create sustainable business models that can support and sustain the 80 percent of U.S. households served by fixed-line broadband (as indicated by an FCC broadband report including data through 2011). Kennedy's observations and suggestions are outlined in our special report.
