"American Wireless Institute
offers the only adequate course of instruction in Wireless Telephone and Telegraph Operation and Engineering. Joining the navy in order to learn the art of wireless is a long, expensive and round about way, but until the establishment of the American Wireless Institute, that was the only satisfactory way of acquiring a wireless education. In six weeks the American Wireless Institute can give to the earnest student as great knowledge of wireless operation as he could acquire during the four years of hard work required of all who enlist in the navy. The demand for competent wireless operators and engineers is in- sistent. One wireless company has stated to us that it will have places for several hundred operators during the next six months.
The great wireless companies are just entering an era of tremendous commercial development which will provide thousands of lucrative positions to men with sufficient wireless training to carry on the work. Write today for our catalogue which shows you how to become master of your destiny. Do it NOW.

"25-word TELEGRAMS, any distance, for 25c.
50-word TELEPOSTS, any distance, for 250c.
100-word TELETAPES, any distance, for 25c.
10-word TELECARDS, any distance, for 10c."
... makes one wonder what the difference between a "TELEGRAM", a "TELEPOST", a "TELETAPE" and a "TELECARD" was ...
“A. RECENT invention in telegraphic instruments has given rise to the Telepost Company, which sends messages at a uniform rate for all distances, and at a rate much lower than is charged by the telegraph companies. It has four kinds of service; viz., telegram, telecard, teletape, and telepost.
“A telegram is a message delivered by a special messenger, as is now done by the other companies.
“A telecard is a telegraphic message printed on a postcard at the delivering office and placed in the post office, and then delivered by the postman on his regular rounds.
A teletape is the perforated strip of paper upon which the instrument records the message at the delivering office. This is mailed and delivered as in the case of a telecard.
A telepost is a telegraphic message printed similarly to a letter at the delivering office and mailed in a sealed envelope and delivered as in the case of the telecard.
“The rates for these services are: a 10-word telecard, 10 cents; a 25-word telegram or a 50- word telepost or a 100-word teletape, 25 cents.” - The Business Letter by Ion E. Dwyer (1914)
Very informative ...
The "uniform rate for all distances" model must have been "disruptive" - and the low price ("a rate much lower ...") - and the product variety (telegram, card, tape, telepost) served different needs :)
Nothing new under the sun ...
