Broadband Customers Are Fanatical, Fickle: Study

High-speed data customers love the product, but two-thirds will drop the provider as soon as they think they can save money with another provider, according to data released Thursday by J.D. Power & Associates. The research firm's 2008 Internet Service Provider Residential Service Customer Satisfaction Study indicated that both cable modem and DSL digital-subscriber line use grew significantly in the past year, to the detriment of dial-up services. Cable modem use is up to 41% from 36% in 2007 while DSL grew to 30% penetration from 27% last year. Dial-up use dropped to 25%, a decline of 10 percentage points from 2007, according to the report.
