#5. Rogers Family
Major holdings: Rogers Communications
Edward and Melinda Rogers have stepped down from active VP roles at the company that bears their name, Rogers Communications Inc. (which owns Canadian Business). But the family remains in control, thanks to founder Ted Rogers’ prescience in keeping near-total control over the company’s Class A voting shares. With the start of a 12-year NHL broadcast deal, the launch of streaming Netflix competitor Shomi and the announcement of a $100 million partnership with Vice Media to launch a TV channel in 2015, the company has made a range of bets to try to protect against the turbulence of the media market.
