In 2014 under chairman Tom Wheeler, the FCC began to increase its scrutiny regarding the use of such agreements—particularly joint sales—to evade its policies. On March 31, 2014, the commission voted to make joint sales agreements count as ownership if the senior partner sells 15% or more of advertising time for its partner, and to ban coordinated retransmission consent negotiations between two of the top four stations in a market. Wheeler indicated that he planned to address local marketing and shared services agreements in the future. The change in stance also prompted changes to then-proposed acquisitions by Gray Television and Sinclair Broadcast Group, who, rather than use sharing agreements to control them, moved their existing programming and network affiliations to digital subchannels of existing company-owned stations in the market, or a low-power station (which are not subject to ownership caps), and then relinquished control over the original stations by selling their licenses to third-parties, such as minority-owned broadcasters.
