Answer:
The answer is: It lacks immediacy that advertisers can get with newspapers or radio.
Explanation:
One of the disadvantages of running an advertisement in a magazine is that it lacks the immediacy that advertisers can get with newspapers or the radio.
Because a magazine is a publication that, unlike a newspaper that is published daily, the magazine is published periodically, which can cause the lack of immediacy that an advertisement would have if it were published in a newspaper or radio for example.
As there is currently a very intense flow of information, depending on the type of product or service to be announced, the immediacy for publication may be more advantageous, as the market is very competitive.
