In addition to programming, BBC Studios produces material to accompany programmes. The company maintained the publishing arm of the BBC, BBC Magazines, which published the Radio Times as well as a number of magazines that support BBC programming such as BBC Top Gear, BBC Good Food, BBC Sky at Night, BBC History, BBC Wildlife and BBC Music. BBC Magazines was sold to Exponent Private Equity in 2011, which merged it with Origin Publishing (previously owned by BBC Worldwide between 2004 and 2006) to form Immediate Media Company.
