Before the January 31, 2010 cross-sell expansion, Mega Millions was the only multi-jurisdictional lottery whose drawings were carried nationally, instead of airing only on stations in participating jurisdictions. Chicago-based cable superstation WGN-TV simulcast Mega Millions drawings on its national WGN America feed immediately following WGN's 9pm (Central Time) newscast. Following the cross-sell expansion, WGN also began airing Powerball drawings nationally. WGN served as a default carrier of both major games where no local television station carried either multi-jurisdictional lottery's drawings. Both drawings were removed from WGN America in late 2014 when it ceased carrying WGN's newscasts.
Once your lottery ticket is purchased, scanned and uploaded to your account, you own the ticket and the rights of the ticket – legally speaking what the agent has after scanning in your ticket is just a piece a paper. (This is why you should never trust a website that claims it is legitimate and does not following the insurance model but does not scan the tickets and send them to you – red flag).
