In late 1999 several other companies began to copy the NetZero free access model including Juno Online Services, (which since August 1996 had offered E-mail but not World Wide Web access for free), Spinway launched with Yahoo! and AltaVista, Freei and BlueLight Internet, which was originally owned by Kmart. They claimed to offer free Internet service forever, in exchange for displaying ads, either on a permanent toolbar or on a "banner" that was shown when online. NetZero sued them for infringing on a banner ad patent. After the dot-com bust in early 2000, NetZero acquired its competitors as each went bankrupt. In addition NetZero acquired AimTV which displayed full video quality 30 second ad spots as well as Simpli and RocketCash.
