This is a current article on Aereo's court battle. I think they should prevail because the 'antenna rental' argument is similar to Cable's argument that DVR services are the same as viewers renting VCR's and DVD machines to make home recordings.
Many stations and networks have simulcast on their home pages. I know a friend who told me he was watching a baseball game on the leagues website a few years back too.
