When anybody registers for an email ID with any of the email service providers, viz. rediffmail.com or yahoo.com, while registering, a person has various options to check in the registration form. If an individual checks those options, these email service providers send various information on sports, news, weather and other subjects to the individual’s email address. This is an example of
(a) Web casting.
(b) Newsletters.
(c) E-mails.
(d) Brochures.
