We Love

"We Love" (also known as "We Love to Entertain You") is the theme song for the Star Force image campaign of German television network ProSieben. Since its introduction several variations of the song have been interpreted by various stars, including Melanie C, Sarah Connor, The Pussycat Dolls and Take That. In 2008, German girl band Monrose recorded their own version of the song, produced by Mozart & Friends, which was released as a digital download single on March 20, 2008 (see 2008 in music).

Writing and recording

Penned by Mozart & Friends writers Alexander Gernert, Manuel Loyo, Alexander Hahn and Alexander Krause, commissioned "We Love" was written and composed in a single week, since the song was needed for a video shooting Monrose had already been booked for at the Hangar 7 in Salzburg, Austria. The track was produced by Hahn and team head Marc Mozart, who said "it was extremely fun to work on this production [...] A&R executives Markus Hartmann and Stefan Harder of ProSieben's music department Starwatch trusted that we'd come up with a hot song, so we enjoyed both a lot of creative freedom while being under the pressure of a short deadline."

Number

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, and so forth. A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels (as with telephone numbers), for ordering (as with serial numbers), and for codes (as with ISBNs). In common usage, the term number may refer to a symbol, a word, or a mathematical abstraction.

In mathematics, the notion of number has been extended over the centuries to include 0, negative numbers, rational numbers such as and , real numbers such as and , complex numbers, which extend the real numbers by including , and sometimes additional objects. Calculations with numbers are done with arithmetical operations, the most familiar being addition, subtraction, multiplication, division, and exponentiation. Their study or usage is called arithmetic. The same term may also refer to number theory, the study of the properties of the natural numbers.

Chat room

The term chat room, or chatroom, is primarily used to describe any form of synchronous conferencing, occasionally even asynchronous conferencing. The term can thus mean any technology ranging from real-time online chat and online interaction with strangers (e.g., online forums) to fully immersive graphical social environments.

The primary use of a chat room is to share information via text with a group of other users. Generally speaking, the ability to converse with multiple people in the same conversation differentiates chat rooms from instant messaging programs, which are more typically designed for one-to-one communication. The users in a particular chat room are generally connected via a shared interest or other similar connection, and chat rooms exist catering for a wide range of subjects. New technology has enabled the use of file sharing and webcam to be included in some programs. This can be considered a chat room.

History

The first online chat system was called Talkomatic, created by Doug Brown and David R. Woolley in 1973 on the PLATO System at the University of Illinois. It offered several channels, each of which could accommodate up to five people, with messages appearing on all users' screens character-by-character as they were typed. Talkomatic was very popular among PLATO users into the mid-1980s. In 2014 Brown and Woolley released a web-based version of Talkomatic.
