傳(chuan)媒(mei)公(gong)(gong)司主要(yao)以媒(mei)體業(ye)(ye)務為主，服務于廣(guang)(guang)大(da)企業(ye)(ye)。有的傳(chuan)媒(mei)公(gong)(gong)司則除(chu)了媒(mei)體業(ye)(ye)務之(zhi)外，還會幫助(zhu)企業(ye)(ye)客戶(hu)進行(xing)活動、專題策劃等，同時(shi)也(ye)會制定媒(mei)體廣(guang)(guang)告投(tou)放(fang)計劃，盡可能推動企業(ye)(ye)客戶(hu)的發展。廣(guang)(guang)告公(gong)(gong)司則與(yu)之(zhi)有點不(bu)同，但經常會有外行(xing)人混(hun)淆這兩(liang)種(zhong)公(gong)(gong)司。準確(que)來說，廣(guang)(guang)告公(gong)(gong)司的業(ye)(ye)務面比傳(chuan)媒(mei)公(gong)(gong)司要(yao)更加寬泛些(xie)，定位(wei)則是(shi)(shi)輔助(zhu)角色(se)，通常自己不(bu)做廣(guang)(guang)告投(tou)放(fang)業(ye)(ye)務，而是(shi)(shi)交給傳(chuan)媒(mei)公(gong)(gong)司，所以說這兩(liang)類公(gong)(gong)司是(shi)(shi)相輔相成的。

受到互聯(lian)網熱潮的影響，人(ren)們(men)從過去的看報紙(zhi)、電(dian)視已轉變為上網、玩手機等(deng)，從而促進不少傳(chuan)統傳(chuan)媒(mei)公(gong)(gong)司(si)的轉型(xing)(xing)。過去傳(chuan)媒(mei)公(gong)(gong)司(si)的業(ye)(ye)務范圍多(duo)在線下進行(xing)，即(ji)報紙(zhi)設計、印(yin)刷、分(fen)發等(deng)，如今也轉型(xing)(xing)到互聯(lian)網新媒(mei)體行(xing)業(ye)(ye)，其(qi)中轉型(xing)(xing)較為成功的則(ze)有(you)人(ren)民日報、新京報等(deng)。與此同時(shi)(shi)，不少手機APP開發商也相繼(ji)開發各類新聞、報紙(zhi)閱讀器，方便人(ren)們(men)隨時(shi)(shi)隨地閱讀，而傳(chuan)媒(mei)公(gong)(gong)司(si)的業(ye)(ye)務也有(you)部分(fen)轉移至此，逐漸形(xing)成穩定的轉型(xing)(xing)行(xing)業(ye)(ye)。
