In our April 21 article titled Satellie Radio Retail Trends Improve In March there was an error in some of the year over year comparisons due to improper input on a data spreadsheet. While the errors were not large, we wanted to make the correct notations.

Please note the following corrections. The opriginal article has also been corrected.
