OHP meaning in News & Entertainment ?

Open House Party (often referred to as OHP) is an American radio show hosted on Saturday and Sunday nights by Kannon. The show promotes itself as "the Biggest Party on the Planet". It focuses on playing contemporary hit radio (CHR) music, also known as Top 40. From its inception in September 1987, OHP quickly became popular with its all-request format, along with a heavy rotation of dance music and remixes that differentiated itself from most Top 40 stations or shows. John Garabedian created and hosted both Saturday and Sunday nights for many years. The show peaked in success from 1998 to 2002, where it was heard on over 175 stations and became the world's most-listened-to radio program. Today, it is broadcast on less than 40 stations, primarily in small markets.

The show typically airs on most affiliates from 7PM to Midnight Eastern Time and 6PM to 11PM Central Time, while most stations in the western half of the US delay the broadcast by two hours. Many stations rebroadcast OHP from midnight to 5:00 a.m. (in Eastern and Mountain Time) or 11:00 p.m. to 4:00 a.m. (in Central and Pacific Time).
