As the Internet came into widespread use, the voting eventually moved from a combination of 900 number telephone voting and filling paper ballots that were either mailed or completed at Pizza Hut locations, to being conducted exclusively on the network's website, and included text messaging by 2007. During the early years of Internet voting, there were several problems, including the digital equivalent of ballot stuffing and adult voting. As a result, a new system was put into place where one vote per Nick.com account is allowed (although it is probable adults still cast votes via the texting option, which is connected to a phone number only rather than a screen name, by creating an account with a false age, or by having their children vote for a chosen subject instead). In 2010, an iPhone application and mobile browser voting were also added.
