In the recent years, there is a push to go green in all the organizations. In an attempt to go green, everyone is avoiding the use of paper in every which way possible. For example, many banks now email you monthly statements in PDF file format instead of the paper statement that they used to mail you. Similarly, many online shopping sites do not send a paper invoice and just email you a PDF invoice.
And now you can download comic books in the electronic formats too. Mainstream comic books are now available through various apps or devices such as Amazon Kindle. On the other hand some of the older comic books (from 1930s, 40s or 50s era) are also available from various old website archives. These comic books or ebooks are available in the CBR and CBZ formats. CBR is a RAR archive containing scanned copy of various pages from the comic book in the JPEG format. Similarly, CBZ is a ZIP archive containing the JPEG images.
