Only if you call 2% "significant"
https://en.wikipedia.org/wiki/NPRWhile NPR does not receive any direct federal funding, it does receive a small number of competitive grants from CPB and federal agencies like the Department of Education and the Department of Commerce. This funding amounts to approximately 2% of NPR's overall revenues.[20]
You get your facts from Wikipedia? The only people I know that listen to NPR are hard core Democrats/Socialists. On NPR's website the latest year they show who they are funded by is 2014:
http://www.npr.org/about-npr/178660742/public-radio-finances1) Federal, state and local taxes-5%
2) Colleges and universities-13% (Democrats)
3) Individuals-34% (more Democrats)
4) Corporations-19% (more Democrats)
5) CPB(Corp. for Public Broadcasting,funded by Congress)-13%
http://www.cpb.org/funding/NPR is just another provider of Democrat propaganda like PBS.
