Segment Financial Results
Revenues
The following table sets forth revenues by segment for the periods presented (in millions):
(1) Revenues for Corporate and Other represent deferred revenue purchase accounting adjustments recorded in accordance with GAAP.
Software Solutions
Revenues were $962.0 million in 2018 compared to $904.5 million in 2017, an increase of $57.5 million, or 6%. Our servicing software solutions revenues increased 7%, or $52.5 million, primarily driven by loan growth on MSP® from new and existing  clients. Our origination software solutions revenues increased 3%, or $5.0 million, primarily driven by growth in our loan origination system solutions and a software license fee in our Lending Solutions business, partially offset by the effect of lower volumes on our Exchange and eLending platforms primarily as a result of the 26% decline in refinancing originations as reported by the Mortgage Bankers Association.
Data and Analytics
Revenues were $154.5 million in 2018 compared to $151.6 million in 2017, an increase of $2.9 million, or 2%. The increase was primarily driven by growth in our property data and multiple listing service businesses, partially offset by upfront revenues from long-term strategic license deals in 2017.
