I work for a large University in a division that provides financial data to ourselves, as well as other academic institutions. We had been a SAS only shop since our inception in the early '90s, save for a few FORTRAN users here and there.
We wanted to support more options for the researchers using our service, and today, we support SAS, R, and Python. One nice thing about SAS is SAS/SHARE. Basically, it makes your native SAS files (*.sas7bdat) available as tables in a database over ODBC or JDBC, with full index support. This has allowed us to consume these same data in both R and Python. This had made many of our younger researchers (think Masters students instead of tenured faculty) very happy!
