During his tenure, Westwood One acquired Metro Networks, the nation's largest provider of traffic, news, weather and sports information, and developed and expanded partnerships with the NFL, NCAA, Notre Dame Football, Wimbledon, USGA, The British Open, The Masters, Marketwatch.com, FOX News, National Academy of Recording Arts and Sciences/The GRAMMYs, and The Academy of Country Music.  Hollander also created new programming and added significant star power to Westwood One's existing programs, including Boomer Esiason and Marv Albert in the NFL Monday Night Football booth, The John Madden Sports Quiz, The Radio Factor with Bill O'Reilly, and The Laura Ingraham Show.  Hollander also extended key Viacom brands with the launch of radio networks with VH1, BET and CMT, and the expansion of the MTV Radio Network.

Prior to joining Westwood One, Hollander was General Manager of WFAN-AM New York.  An original member of the WFAN team, Hollander played a major role in the steady yet spectacular rise of WFAN to its current position as one of the most successful radio stations in the country. Under Hollander's leadership, WFAN rode an unprecedented 11-year streak as the leader in sports talk radio and became the number one revenue generating station in America.

A graduate of Indiana State University, Hollander began his career in radio as an Account Executive in Daytona, Fla.  Born and raised in New York, Hollander returned to the city where he made his way up and down the radio dial.  He served as Account Executive at WBLS-FM and WKTU-FM, as Retail Sales Manager at WAPP-FM and WHN-AM, as Local Sales Manager at WRKS-FM and eventually joining WHN-AM as General Sales Manager.  In 1987, at WHN-AM, the great "experiment" known as Sports Radio was launched and WFAN-AM was born.

Hollander and his wife, Susan, started the CJ Foundation for SIDS in 1993.  The CJ Foundation for Sudden Infant Death Syndrome is a nationwide voluntary health organization dedicated to recognizing the special needs of the SIDS community through funding SIDS research and support services.  Hollander is also on the Board of Directors for Tomorrows Children's Fund, Westwood One, and the Ad Council, as well as an honorary trustee of the Foundation of American Women in Radio and Television.
