Is it legally necessary to constantly use the trademark symbol if the same trademark appears repeatedly in an article or is using the symbol once at the beginning of the article enough?
It is not "legally necessary" to use the trademark symbol EVER (unless you have a license agreement from the owner that says otherwise). However, some registration owners (and… their lawyers) like to show off their ownership, and the occasional use within an article may be used to undermine a later defense of ignorance. However, just the fact that a mark IS REGISTERED is considered "notice to the world" of the rights. It is much more important to use TM (or SM) to signify a claim to ownership of an UN-registered trademark/servicemark, so that readers will understand it is not intended to be a generic or descriptive term and has proprietary value.
To add the trademark symbol in html (â¢) you can call the HTML entity. To do this, you add an ampersand followed either by the entities name, or it's number, and then a se…micolon. Trademark is represented either by ™ or ™. If you want the registered trademark symbol (Â®) you can use either ® or So... Answers® Would give a line similar to the Answers.com logo in the banner on this page.
No; it is too short to qualify as a literary work, and as a work of the federal government it is exempt from copyright protection in accordance with 17USC105.
The Â© symbol is public domain.
The circle-R Â® registered trademark symbol can only legally be used on a trademark that is federally registered. Many non-registered brands use "tm" or "sm" (for service ma…rks) to indicate a claim to the value of the brand. Patents have nothing to do with it.
You can use the trademark â¢ symbol on any unique name or logo you created and use. It does not require special registration yet still signifies your ownership. The Regist…ered symbol Â® is similar to the trademark symbol but it requires registration with the U.S. Patent and Trademark Office (USPTO or PTO). The copyright symbol Â© is similar to the trademark symbol and does not require registration (though it is recommended), however it is for use on intellectual property as opposed to brand names.

Assuming you are referring to the social networking website, the name "twitter" is a legally registered trademark so it should be used with the Â® symbol.
YES because a preson thinked about that naame .....
No; if it's registered, use the R, and if it's not, use the TM.
Facebook is a registered trademark, which earns it the right to use the Â® symbol.
The symbol is considered part of the trademarked word or phrase, so you wouldn't separate them with a comma.
No. Actually, the superscript TM is for designating trademarks in the US that have not yet been registered with the USPTO . If/when you get the trademark registered with …the USPTO, you would use the Â® instead.
Use of the trademark symbol is optional, but it doesn't hurt. For logos it's often part of the image file, so it would actually be more work not to use it. This page is full …of reasonable examples. In the banner we have the Answers logo with TM, and at the very bottom we have a copyright notification, but for running text including the word "Answers" (such as the Answers Properties list header and content), there are no markings. Other websites are almost cartoonishly consistent with their use of the symbol--every logo, every slogan, every time the name of the company or its products appear, there's a helpful (r) reminder in case you'd forgotten in the intervening half-inch that they've registered it all. These are cases where using the indicia is distracting. What you want is a balance.
It's not required to use the trademark or registered trademark symbols, and some designers feel it clutters the look of the packaging.
