Sharing agreements may also be used as a loophole to control television stations in situations where it is legally impossible to own them outright. For instance, FCC regulations only allowed a single company to own more than one full-powered television station in a given market if there are at least eight distinct station owners, and also prohibits the ownership of two or more of the four highest-rated stations (based on total day viewership) in a market. An LMA or similar agreement does not affect the ownership of the station's license, meaning that they do not require the approval of the FCC to establish, and the two stations are still legally considered separate operations from a licensing standpoint. Both Tribune Media and the Gannett Company were required to use shared services agreements as a similar loophole to take control of certain stations in their respective 2013 purchases of Local TV and Belo, as they did not have exemptions to the FCC's newspaper cross-ownership restrictions in the affected markets. Both companies have since spun out their publishing arms as independent companies; the Tribune Publishing Company and Gannett Company. Tegna, who holds the former Gannett's broadcasting and digital media properties, re-acquired the licenses for most of the affected stations following the split. On November 16, 2017, under the Trump administration, the FCC voted in favor of removing the requirement for a market to still have eight distinct station owners in order to allow duopolies, but the prohibition of owning two of the top four stations in a market remains.
