This is our third year publishing the Customer Experience Index (CxPi). The 2007 CxPi and the 2008 CxPi rankings were published in Q4. We decided to publish this year’s CxPi in Q1 2010, so we don’t have a 2009 CxPi.

The 2010 CxPi ranks 133 organizations across 14 industries: Airlines, Banks, Credit Card Providers, Health Plans, Hotels, Insurance Firms, Internet Service Providers, Investment Firms, Parcel Shipping Services (new this year), PC Manufacturers, Retailers, TV Service Providers, Utilities (new this year), and Wireless Carriers.

Barnes & Noble took the top spot for the second year in a row. Marriot Hotels, Hampton Inn, Amazon.com, and Holiday Inn Express round out the top 5. At the other end of the spectrum, Charter Communications landed at the bottom for the third year in a row. Here are the full rankings:
