A multiple listing system (MLS) is an organization with a number of services that real estate agents use to establish contractual offers of collaboration and clearing (between brokers) and collect and disseminate information to enable valuations. The database and software of a Multiple Listing Services is used by real estate agents (or, for example). B, aircraft brokers in other sectors, representing sellers under a list contract, to share information about real estate with other brokers who wish to represent potential buyers or work with a sales agent to find a buyer for the property or asset. The list data stored in the database of a multiple listing is the proprietary information of the broker who obtained a listing agreement with the seller of a property. The 2018 season also saw significant developments in regional broadcast rights, as Chicago Fire and the newly created Los Angeles FC decided to sell their regional television rights exclusively to subscription streaming services (espn and YouTube TV) instead of a local or regional sports network. In addition to a flagship television channel, several teams (including Real Salt Lake and the Seattle Sounders) have also entered into streaming deals in the market.  In 2019, D.C. United also signed a contract with FloSports (which replaced Sinclair Broadcast Group), but the partnership was criticized for the more limited availability of programming and promised that there was no additional coverage that was ever achieved. The team split from FloSports before the final game of the season and signed Sinclair for the 2020 season.  In 2020, Chicago Fire FC also returned to regional linear television with a multi-year contract with WGN-TV, coinciding with the final year of its agreement with ESPN.
 In August 2006, MLS and ESPN announced an eight-year contract for 2007-2014, which gave the league the first rights contract worth $8 million per year. The deal gave the MLS a regular primetime slot on Thursday, television coverage of the first round of the MLS SuperDraft and increased presence on other ESPN features, such as ESPN360 (now ESPN3) and ESPN Mobile.
