My first DSLR was a D70, I bought used. I used it for 4 years before disposing of it. Recently, I uploaded a photo to my gallery and when I checked the EXIF data, if found a copyright by someone else. After removing the photo, I downloaded a reader for EXIF data. Every photo I took with this camera contains this copyright.
I know many of you already know this, but there are many who don't. Comments can be added in your camera. If you buy a used DSLR, remove any comments the previous owner included. My DSLR now includes my copyright statement.

The copyright could be placed in the comments or the EXIF tag for copyright. But there has been a long used tags in digital image in the IPTC/XMP area of the meta data that include the photographers name, contact information and usage right being granted with the copy of the digital image. Nikon, ,Nik, and Adobe recognize these tags and provide access to them. IPTC, International Press Telecommunications Council, is the long established method used by the Newspaper Association of America (NAA) for keeping track of the source of an image. Adobe has established the Extensible Metadata Platform or XMP model and the IPTC is moving toward this open standard.

Curious if you have the copyright or artist name overlaying the photo (I think LR will do this), and you want to send the image to someone for them to use either in computer display (like power point) or print (put in newsletter/monthly publication in print) is there a way to "loose" this information, or is it permanently on the image?

Only if it is edited off of the image. Once it is off the image, there is no other record in the image unless you have completed one of the meta data fields.
Many pros will keep the RAW image and create Jpeg variations for others to use as needed.
An advantage of using the meta data fields is the data is there no matter what conversion or revisions you do to the image.
The XMP/ITPC fields provide more information than just date, and photographer. Some of the other fields include a verbal description of allowed usage. I am aware of a Chicago photographer that created an image of the Chicago lake front skyline for the First Chicago Bank to use on their checks and he was paid for it. A number of years later, First Chicago used the colored image for their credit cards, not a specified use of the image, and the photographer sued and received a settlement for an unauthorized use or copyright violation. The camera will not allow all of the possible fields, but post processing software will provide the access. The cost of the attorney for the original negotiation and later suit were well worth the price for this photographer.
If you have the data in the Exif and someone removes it because it is more technical it might build a stronger case for the theft of intellectual property.
