(Mike Mozart)With Comcast losing pay-TV subscribers in favor of streaming video services, the company is doing what it can to retain customers who not only ante up for TV and broadband, but also for home phone service. Today, the company confirmed that some of its Mid-Atlantic and New England broadband customers will be getting free speed upgrades. Comcast is trying to sweeten the pot to retain Triple Play (TV/Internet/Phone) customers, who account for about 45% of its subscriber base, by bumping some of them up from 25Mbps service to the new Performance Pro tier at 75 Mbps at no extra cost. Note that the company’s press release only refers to “eligible Triple Play subscribers” but provides no further details on eligibility.
