Newspapers and magazines are print publications issued at regular intervals over time. Historically, newspapers were usually issued daily or weekly, but sometimes semi-weekly (twice a week), bi-weekly (every two weeks), or monthly. Magazines, in contrast, were usually issued weekly, bi-weekly, monthly, or quarterly (four times a year). Both newspapers and magazines could be purchased by subscription (an arrangement whereby the reader pays in advance for a year of issues), or individually, often at news-stands, grocery stores, book stores, train stations, and other places.
