Internet Addiction

Internet addiction disorder (IAD), or, more broadly, Internet overuse, problematic computer use or pathological computer use, is excessive computer use that interferes with daily life. These terms avoid the distracting and divisive term addiction and are not limited to any single cause.

Online activities which, if done in person, would normally be considered troublesome, such as compulsive gambling or shopping, are sometimes called net compulsions.[4] Others, such as reading or playing computer games, are troubling only to the extent that these activities interfere with normal life. Supporters of disorder classification often divide IAD into subtypes by activity, such as excessive, overwhelming, or inappropriate pornography use, gaming, online social networking, blogging, email, or Internet shopping.

Corrective strategies include content-control software, counseling, and cognitive behavioural therapy. One of the major reasons that the Internet is so addicting is the lack of limits and the absence of accountability.
