Providence Equity Partners Inc. is one of three private equity firms that have placed bids for the Travel Channel, Reuters reported Thursday.

Providence Equity, Kohlberg Kravis Roberts & Co., and Thomas H. Lee Partners L.P. each submitted separate bids in an auction that is expected to see Travel Channel Media, owned by Atlanta-based Cox Communications Inc., sell for between $600 million and $700 million, according to Reuters, which did not identify its sources. The funds declined to comment.
