Nielsen Holdings, a market research giant, filed Thursday for a $1.75 billion initial public offering.
Taken private in 2006 in a $10 billion leveraged buyout by six private equity firms led by Thomas H. Lee Partners and Kohlberg Kravis Roberts, Nielsen is the most notable of recent private-equity backed listings.
In its prospectus, the company said it had revenue of $4.8 billion last year, with a net loss of $489 million — about $100 million less than the previous year.
