There are several options for viewing live TV online, according to Tom's Guide. Sling TV and local news sites allow viewers to watch live broadcasts. Ustream shows live TV as well as live video streams that are not available on TV.
Sling TV works similar to cable or satellite television, but it is only available online. Members begin with a basic package and add preferred viewing options as desired. The basic package has around 20 channels, but add-on packages, like kids channels or sports, cost extra.
Many local TV news channels stream their broadcasts live on their websites.
Ustream offers live viewing of networks like CBS and PBS.
